Israel further tightened its blockade of the Gaza Strip on Tuesday, preventing fuel deliveries through its only goods crossing with the Palestinian enclave after scores of kites carried firebombs across the border.

The defence ministry announced the move on Monday after saying last week it was closing the crossing to most deliveries, citing the kites and balloons that have for months carried firebombs into Israel from Gaza.

Fuel deliveries will be suspended until Sunday, the ministry said in a statement. The fishing zone enforced by Israel off the Gaza Strip will also be reduced from six nautical miles to three.

The goods crossing, known as Kerem Shalom, will remain open for food and medicine on a case-by-case basis.

“In light of the continued terror efforts of Hamas, Defence Minister Avigdor Lieberman has decided, after consulting with the chief of [military] staff, to close Kerem Shalom for the passage of fuel and gas until Sunday,” a statement said.

Islamist movement Hamas, which runs the Gaza Strip and has fought three wars with Israel since 2008, denounced the move.

It had called the initial closing last week a “crime against humanity”.
