JERUSALEM, Aug 2 (Reuters) - At least three rockets or mortar bombs struck in and around Israel's southern port of Eilat on Monday but caused no casualties, Israel Radio reported, citing initial information received from emergency services.

Israel's Army Radio said five rockets were believed to have been fired, one of them landing inside neighbouring Jordan.

An Israeli police spokesman confirmed only that a number of a explosions were heard around the Eilat area.

There had been no reports of casualties or damage, the spokesman said.

Both Israel Radio and Army Radio said some of the suspected rockets appeared to have overshot their land targets and landed in the Red Sea. The Israeli military, which is resposible for waters off Eilat, said it was investigating.

Eilat, the Jordanian port of Aqaba and nearby Egyptian Red Sea resorts have seen violence attributed to Islamist militants. At least one rocket struck Aqaba on April 22, causing no casualties. Amman said the rocket had been fired from outside Jordan and Israeli media spoke of the Egyptian Sinai as a possible launch point.

In 2005, rockets were fired at U.S. warships in Aqaba's port but missed their target and killed a Jordanian soldier on land. A group claiming links to al Qaeda said it was behind the attack.

Two years later, a Palestinian suicide bomber infiltrated through the Sinai and killed three people at an Eilat bakery.

Jordan and Egypt are the only Arab states to have full peace accords with Israel. Those ties were frayed by Israel's crackdown in 2000 on a Palestinian uprising in the West Bank and Gaza Strip.
