LONDON

The EU's foreign policy chief on Saturday expressed "regret" over the resumption of Israeli attacks on the Gaza Strip, emphasizing Tel Aviv's obligation to respect international humanitarian law and the laws of war, which he described as "not only a moral obligation but also a legal one."

"The way Israel exercises its right to self-defence matters. It's imperative that Israel respects International Humanitarian Law and the laws of war," Josep Borrell wrote on X.

His remarks came after the Israeli army resumed attacks on Gaza after declaring the end of a week-long humanitarian pause on Friday morning, for which Borrell expressed regret, fearing that the already high civilian death toll would rise further.

Reiterating his call for Israel to respect international law, he stressed that this is "not only a moral obligation but a legal one as well."

He also mentioned the increasing violence in the occupied West Bank. Citing the UN figures, Borrell said 271 Palestinians have been killed by Israelis since Oct. 7.

"It's not sufficient humanitarian pauses should be resumed, while simultaneously working towards a comprehensive political solution for all the Palestinian territories," he added.

The Israeli army resumed bombing the Gaza Strip early Friday after ending a week-long humanitarian pause with the Palestinian resistance group Hamas.

At least 178 Palestinians have been killed and 589 injured on Friday in Israeli airstrikes, according to the Gaza Health Ministry.

The humanitarian pause began on Nov. 24 as part of an agreement between Israel and Hamas to temporarily halt fighting to allow hostage swaps and aid delivery.

More than 15,000 Palestinians, mostly children and women, have been killed in Israeli attacks since Oct. 7 following a cross-border attack by Hamas.

Around 1,200 Israelis have also been killed, according to official estimates.
