The Ansar Al-Suna terror group, affiliated with Al-Qaida, said earlier that its terrorists had fired at the Israeli workers.

Sources in Gaza said Tuesday night that the IDF fired seven mortar shells into the Sage'a neighborhood in central Gaza, injuring several Gaza Arabs. One of the injured was said by Gaza medical workers to be in critical condition, but the IDF has not confirmed the report.

The IDF said the shelling was in response to earlier shooting by Gaza Arab terrorists at Israeli workers who were conducting engineering work near the Gaza border fence. After the attack, IDF soldiers protecting the workers fired over the fence at the source of the shooting.

A short time later, Gaza Arab terrorists attempted to attack a second time. Three terrorists snuck up to an area near the security fence, positioning themselves to attack the Israeli workers. IDF soldiers again fired in the direction of the terrorists, but it was not clear if any were hit.

The Ansar Al-Suna terror group, affiliated with al-Qaeda, said earlier that its terrorists had fired at the Israeli workers.

The last IDF action against Gaza Arab terrorists occurred on Saturday night, when IDF planes attacked three targets in Gaza where rockets and other weapons for use against Israel were being manufactured. Two smuggling tunnels running from Sinai to Gaza were also destroyed.
