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 its trucks were stolen.

UN agency says most of its attempts to deliver aid to northern Gaza have been denied by Israeli forces even as looting of convoys has continued
