The rocket attacks on Friday night and Saturday morning followed days of clashes at Jerusalem’s flashpoint Al-Aqsa mosque compound and a month of deadly violence.

The unrest — which comes as the Jewish festival of Passover overlaps with the month of Ramazan — has sparked international fears of a wider conflict, one year after similar violence led to an 11-day war between Israel and Gaza-based militants.

“Following the rockets fired toward Israeli territory from the Gaza Strip last night, it was decided that crossings into Israel for Gazan merchants and workers through the Erez Crossing will not be permitted this upcoming Sunday,” said COGAT, a unit of the Israeli defence ministry responsible for Palestinian civil affairs.

Two rockets were fired from Gaza at southern Israel on Friday night, one of them hitting the Jewish state and the other falling short and striking near a residential building in northern Gaza, Palestinian and Israeli sources said.

A third rocket was fired at Israel on Saturday morning, the army said, with no air raid sirens activated for any of the launches.

They followed rocket attacks on Wednesday and Thursday, and came as Israeli police clashed with Palestinian protesters at Al-Aqsa mosque, leaving at least one man hospitalised in serious condition.

Israel had retaliated against those attacks with air strikes, but in an apparent desire to prevent further violence, shifted its response this time to the painful economic measure of closing Erez, implying that further rockets would extend the penalty.

“The re-opening of the crossing will be decided in accordance with a security situational assessment,” COGAT added.
