A Grad rocket was fired from the Gaza Strip and exploded near Ashdod late on Wednesday. There were no reports of injuries, but a number of people were treated for shock.

Sirens went off in Rehovot, Rishon Letzion and other cities in the area and the residents were told to take shelter.

Earlier this month, An Israeli air strike wounded three Palestinians in the northern Gaza Strip. An Israeli military spokeswoman said the air strike targeted a militant squad that was preparing to launch rockets across the border into Israel.

The Israel-Gaza border has been mostly quiet since the Israel and Hamas agreed to a ceasefire after five days of cross-border violence in August.

It is still unclear which Palestinian group launched the rockets. However, Israeli intelligence officials believe that Hamas has no interest in escalation, as it is trying to leverage its success in bringing about the release of thousands of Palestinian prisoners, and are not behind the rocket attacks. Officials believe that a small faction is behind the attacks, which contradicts Hamas’ current policy in the Strip.
