The International Committee of the Red Cross (ICRC) said it was deeply troubled that its humanitarian convoy in Gaza City came under fire on Tuesday.

A convoy of five trucks and two ICRC vehicles was carrying lifesaving medical supplies to health facilities when it was hit by fire, the organization said in a statement, adding that two trucks were damaged and a driver was lightly wounded.

"These are not the conditions under which humanitarian personnel can work," William Schomburg, head of the ICRC sub-delegation in Gaza, said. "We are here to bring urgent assistance to civilians in need. Ensuring that vital aid can reach medical facilities is a legal obligation under international humanitarian law."
