The United Nations on Monday said that Israel has attacked a building housing UN staff in the southern part of the Gaza Strip.
The attack near the Rafah border crossing was another indication that no place in Gaza is safe.
Not the north, not the centre and not the south, said Philippe Lazzarini, commissioner general of the UN Relief and Works Agency for Palestine Refugees in the Near East (UNRWA).
The UNRWA said it had sent the coordinates of the building’s location to all parties to the conflict twice, most recently on Friday.
The information could not initially be independently verified.
According to the UNRWA, four UN employees were being housed in the guest house and had left the building shortly before the attack, otherwise they would have all been killed in the attack, it said.
Displaced people were not being accommodated in the building, it added.
According to UN figures, more than 1.5 million people have been displaced as a result of the fighting in the Gaza Strip.
The UNWRA said more than 60 UN facilities had been directly or indirectly damaged in recent weeks.
Most of these are schools, which are now being used as emergency shelters.
More than 600,000 people are said to have sought refuge in UNRWA buildings in the southern Gaza Strip.
