The Israeli military shed light Wednesday on the circumstances surrounding the deaths early this year of six male hostages who were found shot in a Gaza tunnel—and whose captors were also found dead at their side.

Israeli airstrikes tore through a tent camp for displaced Palestinians in southern Gaza on Wednesday, sparking fires and killing at least 21 people, according to the head of a nearby hospital, in the latest assault on a sprawling tent city that Israel designated a humanitarian safe zone but has repeatedly targeted.

At least 200 people were killed in Israeli airstrikes on northern Gaza Saturday, according to local health officials, as the United Nations said it would pause aid deliveries through the enclave’s main crossing after its trucks were stolen.
