JERUSALEM/GAZA, July 27 (Reuters) - Israel said on Sunday it would halt military operations for 10 hours a day in parts of Gaza and allow new aid corridors as Jordan and the United Arab Emirates airdropped aid to the enclave, where images of starving Palestinians have alarmed the world.

The Israeli military has intercepted a Gaza-bound aid ship, detaining 21 international activists and journalists and seizing all cargo, including baby formula, food, and medicine, according to the Freedom Flotilla Coalition.

Israel’s military said it fired warning shots to distance a crowd “in response to an immediate threat” and it was not aware of any casualties.

Yechiel Leiter, Israel's ambassador to the United States, joins "Elizabeth Vargas Reports" to discuss the humanitarian crisis in Gaza, and suggests the United Nations is responsible for aid not being distributed due to the NGO's desire to collaborate with Hamas,

The U.N. says it’s unable to bring in enough aid to Gaza as it is hindered by Israeli restrictions and a breakdown of security.

"The humanitarian catastrophe that we are witnessing in Gaza must end now," a joint statement from the three countries reads.

Some of Israel’s closest allies have stepped up criticism of its restrictions on aid to Gaza, where doctors and aid organizations say people are dying of starvation.
