The U.N. has halted aid deliveries to Gaza through the main crossing as security concerns mount. Aid has been slow to get into the Palestinian territory, causing widespread hunger. Debora Patta reports.

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.

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