evidence: Dozens of families in the southern city of Rafah in the Gaza Strip were left homeless Saturday after Israeli forces struck one of the largest residential towers there, asserting that the block is used by Hamas to plan attacks on Israel. [...] Israel’s latest attack is increasing pressure on the last part of the enclave that it has not yet targeted, where upwards of 1 million displaced Palestinians are sheltering. One of the 300 residents of the tower, which is located some 500 meters (1,640 feet) from the border with Egypt, told Reuters that Israel gave them a 30-minute warning to flee the building at night.
