At least five people are dead after Gaza police tried to disarm a leftover bomb in Beit Lahiya this morning, reports the AP. Among the mortally wounded, according to the Palestinian Ministry of Health via the the New York Times: a Palestinian translator, three Gaza police officers, and 35-year-old AP videojournalist Simone Camilli, who is the first foreign journalist killed in the conflict. Four others were said to be injured, including AP photographer Hatem Moussa; he and Camilli, an Italian national, were on assignment. The bomb reportedly went off at 10:45am local time—just hours before a three-day Egypt-proposed ceasefire between Israel and Hamas is set to expire, notes the Times. (More Gaza explosion stories.)
