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 convoys. It blamed the breakdown of law and order in large part on Israeli policies.

In Israel, a former defense minister and fierce critic of Prime Minister Benjamin Netanyahu — and a hard-liner on the Palestinians — accused the government of ethnic cleansing in northern Gaza, where a military offensive continues.
