Israeli air strikes in Gaza killed at least 200 people, Palestinian health authorities said, as attacks hit dozens of targets early on Tuesday, ending a weeks-long stand-off over extending the ceasefire that halted fighting in January.
Strikes were reported in multiple locations, including northern Gaza, Gaza City and the Deir al-Balah, Khan Younis and Rafah in central and southern Gaza Strip. Palestinian health ministry officials said many of the dead were children.
The Israeli military, which said it hit dozens of targets, said the strikes would continue for as long as necessary and would extend beyond air strikes, raising the prospect that Israeli ground troops could resume fighting.
The attacks were far wider in scale than the regular series of drone strikes the Israeli military has said it has conducted against individuals or small groups of suspected militants and follows weeks of failed efforts to agree an extension to the truce agreed on January 19.
In hospitals strained by 15 months of bombardment, piles of bodies in white plastic sheets smeared with blood could be seen stacked up as casualties were brought in.
The Palestinian Red Crescent said its teams dealt with 86 killed and 134 wounded, but others were brought to overwhelmed hospitals by private cars.
