Tens of thousands of Palestinians streamed into the most heavily destroyed part of the Gaza Strip on Monday as Israel lifted its closure of the north for the first time since the early weeks of the 15-month war with Hamas in accordance with a fragile ceasefire.

Gaza's Hamas authorities said more than 300,000 people, or almost half of those displaced from the north during the war, had crossed into Gaza City and the north edge of the enclave.

Nader Shamalakh had seen and heard Israel’s bombardment and invasion of Gaza City — that’s what sent him and his family fleeing south.
