An official says Gaza's rescue service has evacuated more than 4,000 people from homes flooded after four days of heavy rain across the territory.

The downpour continued Saturday. It's part of a storm that covered Jerusalem and some of the West Bank with thick snow.

In Gaza, some of those trapped by rising waters were evacuated by fishing boats. A local TV station showed a rescuer standing on the shoulders of another man in a boat as they tried to reach people in a third-floor apartment.

Mohammed al-Madaina of the Gaza rescue service says efforts were hampered by lack of fuel and power, a result of a tightened Egyptian border closure. Israel and Egypt have restricted access to Gaza since the Islamic militant Hamas seized the territory in 2007.
