Rescuers in Gaza raced to dig victims from the rubble on Sunday after Israeli airstrikes on two school buildings left at least 30 people dead, according to the Palestinian Civil Defense. The strikes continue a bloody weekend, after a similar lethal attack on Saturday.

The Israel Defense Forces (IDF) and the Israel Security Agency have taken responsibility for the strike, saying that they were targeting “terrorists operating inside Hamas command and control centers” that were “embedded” within the schools.

“If a warning had been given, the number of deaths would have been lower,” Basal said.

Sunday’s strike follows a series of strikes on the Al-Huda and Al-Hamama schools — also targeting alleged Hamas infrastructure, according to the IDF — that left at least 17 dead on Saturday.

In that case, Basal said, “the first bombing was unexpected and resulted in a large number of martyrs and injured individuals. While the martyrs and injured were being retrieved, the occupation forces issued a warning that another strike was imminent.”

The death toll from Israeli military action in Gaza since October 7 reached 39,583 on Sunday, with a further 91,398 people injured, according to the Ministry of Health in Gaza. Israel launched the action in Gaza following the Hamas attacks, wihich killed around 1,200 people.
