Palestinian militants in Gaza have fired missiles into Israel for the third day running.

The Israeli army said three missiles had been fired. No injuries or damage have been reported. Islamic Jihad said it was behind the attack.

Despite the recent clashes, including Israeli army raids in which seven militants were killed, both sides say they are committed to a truce.

This has largely held since June, greatly reducing the level of violence.

Both sides have sought to contain the fallout from recent fighting while accusing each other of breaching the truce.

A period of quiet in Gaza was shattered Tuesday when Israel launched a brief incursion into Gaza to destroy what the army said was a tunnel militants had dug near the border to kidnap Israeli soldiers.

Six militants were killed during the Israeli operation and militants fired dozens of rockets in response.

On Wednesday, a militant was killed in an Israeli air strike after two rockets were fired at an Israel.
