Israeli police say Palestinian militants have fired six rockets at southern Israel.

Spokesman Micky Rosenfeld says the rockets landed in open areas, and no one was injured.

The attack came as Britain's foreign minister, David Miliband, planned to visit the southern Israeli town of Sderot. It was not known whether he was in the area at the time of the attack.

The Islamic Jihad militant group in the Gaza Strip claimed responsibility.

The rockets were the latest salvo in nearly two weeks of violence that has severely strained a 5-month-old cease-fire between Israel and Gaza's Hamas rulers.
