People mourn over the bodies of the Palestinian journalists Abd Shaat and Mohamed Qeshta, who were killed in an Israeli strike on a vehicle, before their funeral at Shifa Hospital, in Gaza City, Wednesday, Jan. 21, 2026. (AP Photo/Jehad Alshrafi)2026-01-21T13:41:01Z CAIRO (AP) Israeli forces on Wednesday killed at least 11 Palestinians in Gaza, including two 13-year-old boys, three journalists and a woman, hospitals said, on one of the war-battered enclave s deadliest days since the ceasefire between Hamas and Israel took effect in October.The United States is trying to push the deal forward and implement its challenging second phase.Among the dead were three Palestinian journalists who were killed while filming near a displacement camp in central Gaza, a camp official said. Israels military said it had spotted suspects who were operating a drone that posed a threat to its troops.The two boys were killed in separate incidents. In one, a 13-year-old, his father and a 22-year old man were hit by Israeli drones on the eastern side of the Bureij refugee camp, according to officials from Al-Aqsa Martyrs Hospital in the central town of Deir al-Balah, which received the bodies.It wasnt immediately clear whether the three had crossed into Israeli-controlled areas. A mounting death tollThe other 13-year-old was shot by troops in the eastern town of Bani Suheila, Nasser Hospital said after receiving the body. In a video circulated online, the father of Moatsem al-Sharafy is seen weeping over it.The boys mother, Safaa al-Sharafy, told The Associated Press that he had left to gather firewood so she could cook.He went out in the morning, hungry, she said, tears running down her cheeks. He told me hed go quickly and come back.Later Wednesday, an Israeli strike hit a vehicle carrying the three Palestinian journalists who were filming a new displacement camp managed by an Egyptian government committee in the Netzarim area, said Mohammed Mansour, the committees spokesperson.Mansour said the journalists were documenting the committees work and that the strike occurred about 5 kilometers (3 miles) from the Israeli-controlled area. He said the vehicle was known to Israels military as belonging to the committee. Video footage showed the charred and smoking vehicle by the roadside. One journalist killed, Abdul Raouf Shaat, was a regular contributor to Agence France-Presse but he was not on assignment for it at the time, the news agency said.Abdul was much loved by the AFP team covering Gaza. They remember him as a kind-hearted colleague, the agency said in a statement that demanded a full investigation into his death.According to the Committee to Protect Journalists, more than 200 Palestinian journalists and media workers have been killed in Gaza since the war began in 2023, including visual journalist Mariam Dagga, who worked for the AP and other news organizations.Nearly five months after the strikes on a hospital that killed Dagga and four other journalists, the Israeli military says it is continuing to investigate.Aside from rare guided tours, Israel has barred international journalists from entering to cover the war. News organizations rely largely on Palestinian journalists in Gaza as well as residents to show what is happening. Nasser Hospital officials also said Wednesday they received the body of a Palestinian woman shot by Israeli troops in the Muwasi area of the southern city of Khan Younis, which is not controlled by the military.In a separate attack, three brothers were killed in a tank shelling in the Bureij camp, according to Al-Aqsa Martyrs hospital.More than 470 Palestinians have been killed by Israeli fire since the ceasefire took effect on Oct. 10, according to Gazas health ministry. At least 77 have been killed by Israeli gunfire near a ceasefire line that splits the territory between Israeli-held areas and most of Gazas Palestinian population, the ministry says.The ministry, which is part of the Hamas-led government, maintains detailed casualty records that are seen as generally reliable by U.N. agencies and independent experts. A mothers pleaThe first phase of the October ceasefire that paused two years of war between Israel and Hamas militants focused on the return of all remaining hostages in exchange for the release of hundreds of Palestinian detainees and a partial withdrawal of Israeli forces in Gaza.All but one hostage, living or dead, have been returned to Israel. Ran Gvili, a 24-year-old police officer known as Rani, was killed while fighting Hamas militants during the Oct. 7, 2023 attack that started the war.His relatives on Wednesday called again on Israels government and U.S. President Donald Trump to ensure the release of his remains.We need to continue to amplify Ranis voice, explain about him, talk about him, and explain to the world that we, the people of Israel, will not give up on anyone, his mother, Talik Gvili, said. She told the AP the family doesnt really know where he is.Hamas said Wednesday it has provided all information it has on Gvilis body to the ceasefire mediators, and accused Israel of obstructing search efforts in areas it controls in Gaza. Israel targets more sites in LebanonIsraels air force carried out multiple strikes Wednesday against sites in southern Lebanon that it said the militant Hezbollah group used to store weapons, and at sites along Lebanons border with Syria where it said weapons were being smuggled.The military said it struck four border crossings in Lebanons northeastern region of Hermel.Earlier, strikes in three villages in southern Lebanon targeted weapons storage facilities. Israels military said it had issued warnings to evacuate. Lebanons health ministry said 19 people, including journalists, were wounded in the southern village of Qennarit, south of the port city of Sidon.Lebanese officials condemned the strikes in southern Lebanon, which President Joseph Aoun called systematic aggression.In addition, drone strikes on cars in the villages of Bazouriyeh and Zahrani killed two people, according to state-run National News Agency.The strikes were the latest in near-daily Israeli military action since a ceasefire more than a year ago ended the 14-month Israel-Hezbollah war. The agreement included a Lebanese pledge to disarm militant groups, which Israel says has not been fulfilled.___Associated Press writer Bassem Mroue in Beirut contributed to this report.

(NASA via AP)2026-01-21T21:19:38Z CAPE CANAVERAL, Fla. (AP) The astronauts evacuated last week from the International Space Station say a portable ultrasound machine came in super handy during the medical crisis.During their first public appearance since returning to Earth, the four astronauts refused Wednesday to say which one of them needed medical attention and for what reason. It was NASAs first medical evacuation in 65 years of human spaceflight.NASAs Mike Fincke said the crew used the onboard ultrasound machine once the medical problem arose Jan. 7, the day before a planned spacewalk that was abruptly canceled. The astronauts had already used the device a lot for routine checks of their body changes while living in weightlessness, so when we had this emergency, the ultrasound machine came in super handy. It was so useful that Fincke said there should be one on all future spaceflights. It really helped, he said. Of course, we didnt have other big machines that we have here on planet Earth, he added. We do try to make sure that everybody before we fly are really, really not prone to surprises. But sometimes things happen and surprises happen, and the team was ready ... preparation was super important. The space station is set up as well as it can be for medical emergencies, said NASAs Zena Cardman, who commanded the crews early return flight with SpaceX. She said NASA made all the right decisions in canceling the spacewalk, which would have been her first, and prioritizing the crews well-being. Japanese astronaut Kimiya Yui said he was surprised how well all the preflight training paid off in dealing with the health concerns.We can handle any kind of difficult situation, Yui said. This is actually very, very good experience for the future of human spaceflight.Joining them on what turned out to be a 5 1/2-month mission more than a month shorter than planned was Russias Oleg Platonov. They launched last August from Florida and splashed down in the Pacific off the San Diego coast last week. Welcoming them back to Houston were their replacements, who arent due to launch until mid-February. NASA and SpaceX are working to move up the flight.We were hoping to give them hugs in space, but we gave them hugs on Earth, Fincke said.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institutes Department of Science Education and the Robert Wood Johnson Foundation.

Tear gas is deployed as Federal agents make arrests on Wednesday, Jan. 21, 2026, in Minneapolis. (AP Photo/Angelina Katsanis)2026-01-22T02:55:53Z WASHINGTON (AP) The U.S. Army has ordered several dozen additional active-duty soldiers to prepare for a possible deployment to Minneapolis if needed, a defense official said Wednesday, amid protests over the Trump administrations immigration enforcement crackdown.The defense official, who spoke on condition of anonymity to discuss sensitive plans, confirmed that members of an Army military police brigade who are stationed at Fort Bragg in North Carolina have been given prepare-to-deploy orders. If deployed, the troops would likely offer support to civil authorities in Minneapolis, according to the official, who stressed that such standby orders are issued regularly and they do not necessarily mean that the troops would end up going.About 1,500 active-duty soldiers from the Armys 11th Airborne Division based in Alaska also have received similar standby orders. President Donald Trump has threatened to invoke the Insurrection Act, a rarely used 19th century law that would allow him to use active-duty troops as law enforcement. That threat followed protests that erupted in Minneapolis after a federal immigration officer killed resident Renee Good on Jan. 7. Trump quickly appeared to walk back the threat, telling reporters a day later that there wasnt a reason to use the act right now. If I needed it, Id use it, Trump said. Its very powerful. When asked about the latest orders, which were reported earlier by MS Now, the Pentagon said it didnt have information to provide at this time.Minnesota Gov. Tim Walz, a Democrat and frequent target of Trump, has urged the president to refrain from sending in more troops and, in a statement Tuesday, invited him to visit Minnesota and help restore calm and order and reaffirm that true public safety comes from shared purpose, trust, and respect.In his second term, Trump has pushed traditional boundaries by using troops in American cities, often over the objections of local officials, amid federal operations targeting illegal immigration and crime. Trump deployed federalized National Guard troops to Los Angeles last June after protesters took to the streets in response to a blitz of immigration arrests. Ultimately, he sent about 4,000 Guard members and 700 active-duty Marines to guard federal buildings and, later, to protect federal agents as they carried out immigration arrests.He also mobilized Guard troops in places like Chicago and Portland, Oregon, but has faced a series of legal setbacks. Trump said in December that he was dropping that push for the time being. RSShttps://feedx.net https://feedx.site
