(AP) — Israeli warplanes are striking targets across Gaza ahead of an expected ground offensive in the besieged Hamas-ruled territory.

Fears of a widening war have grown as Israel struck targets in the occupied West Bank, Syria and Lebanon and traded fire with Lebanon’s Hezbollah militant group.

Two aid convoys arrived in the Gaza Strip over the weekend through the Rafah crossing from Egypt. Israel said the trucks carried food, water and medical supplies. Israel has not allowed in fuel, which is critically needed for water and sanitation systems and hospitals.
