Gaza - A driver and another worker bringing humanitarian supplies from the northern crossing point of the Gaza Strip into the territory was killed when the aid convoy came under Israeli fire, a spokesman for the United Nations said.
The UN agency for Palestinian refugees, UNRWA, said it was subsequently suspending all its activity in the enclave.
In a second incident later in the day another UN convoy with international staff, heading from Gaza City to the southern town of Rafah, also came under fire, and one more person was injured.
