Israel’s military has said the ceasefire is back on in Gaza after it carried out heavy air strikes overnight across the Palestinian territory that killed 104 people, including 46 children, according to local health officials.

The strikes – the deadliest since the ceasefire began on October 10 – marked the most serious challenge to the tenuous truce to date.
