He worked as a cameraman for Al Jazeera Mubasher.The journalist was killed when an Israeli air attack hit a house. Two other Palestinians were also killed in the strike as Israel has continued its attacks despite an October “ceasefire”.Wishah gained prominence during the Gaza war by accompanying and filming footage for his late brother, an Al Jazeera Mubasher correspondent killed on April 8.Together, they formed a media duo that documented the suffering of the Palestinian people and the unfolding events of the war.In an interview after his brother’s death, Wishah called on the world to stop the killing of journalists.“Let the martyrdom of Mohammed Wishah be the end to the killing of journalists. This is my message to the world. Someone should stop the occupation from targeting journalists. That’s our only message: Stop the Israeli occupation from targeting journalists,” Ahmed said in April.Ahmed’s dedication to his brother extended far beyond his journalistic duties.After Mohammed’s death, he also took care of his late brother’s children and took on additional responsibilities within their family.What have colleagues said about him?Talal Mahmoud, an Al Jazeera Mubasher correspondent in Gaza, recalled his close ties with the two brothers.“I’ve known Ahmed since the beginning of the war. He was always present, accompanying his brother Mohammed in the tent where he stayed,” Mahmoud said.“Given our shared work, we frequently gathered in that tent at Al-Aqsa Martyrs Hospital or al-Awda Hospital in Nuseirat camp, exchanging thoughts and discussing the details of our coverage.”“He became not just a friend but a colleague at the same channel. He would often accompany me on assignments, documenting the events we covered throughout the long months of this war.”
