It went on to condemn the strike and said "the global silence regarding attacks on students and universities serves as encouragement for the continuation of these crimes".

"This strike occurs at a time when the higher education sector is facing total annihilation, with 95 percent of the buildings belonging to academic institutions having been damaged as a result of the war," it continued.

"This heinous assault is part of a continuous series of attacks on education; over the past six days, 10 students and educators have been killed by the occupation's fire."

A truce has been in effect in Gaza for over a year, but has failed to completely halt the violence there.

Gaza civil defence spokesman Mahmoud Bassal said four other people were killed on Sunday, two in an airstrike in the southern city of Khan Yunis, one in central Deir al Balah and one in the north of the Strip.
