The U.N. agency for Palestinian refugees says it is halting aid deliveries through the main cargo crossing into Gaza because of the threat of armed gangs who have looted recent convoys.

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 more of its trucks were stolen.

Mughrabi CAIRO (Reuters) -Israeli military strikes killed at least 15 Palestinians in Gaza on Sunday, medics said, as Israeli forces kept up bombardments across the enclave and blew up houses on its northern edge.
