Five Palestinian journalists have been killed in an Israeli airstrike on their vehicle in central Gaza, their employer has said, as renewed ceasefire negotiations between Hamas and Israel have reportedly reached an impasse.

Faisal Abu al-Qumsan, Ayman al-Jadi, Ibrahim al-Sheikh Khalil, Fadi Hassouna and Mohammed al-Lada’a were sleeping in their broadcasting truck, marked as press, when it was targeted in a direct strike by the Israeli military, witnesses told Palestinian media. Another 16 people were killed in other Israeli pre-dawn strikes across the territory, the local health ministry said.
