Israeli forces killed a Palestinian journalist on Sunday, weeks after he received threatening messages instructing him to stop filming Israeli attacks in the Gaza Strip.

The Israeli military sent tanks and troops into the camp in the northern Gaza Strip late on Saturday following a night of heavy air strikes. It marked the military’s third ground assault on Jabalia since the war on Gaza began a year ago.

Hassan Hamad, 19, died when his home in Jabalia refugee camp was struck by artillery fire. Hamad was reporting on the new Israeli incursion just moments before he was killed.
