More Saudi attacks 'imminent', says US

US diplomats, warning that more attacks in Saudi Arabia were “imminent,” closed their embassy and consulates in the oil rich kingdom today.

Investigators believed about 50 hard-core Muslim militants were ready to volunteer for suicide strikes like the ones that targeted Westerners in the capital Riyadh last week, said a Saudi official.

“The Embassy continues to receive credible information that further terrorist attacks are being planned against unspecified targets in Saudi Arabia,” Americans were warned in a statement posted on embassy and consulate web sites.

“In response to information that some strikes may be imminent, the embassy in Riyadh and the consulates in Jiddah and Dhahran will be closed” on Wednesday.

The statement said diplomatic offices would reopen on Sunday.

Earlier, a Saudi official said the 50 militants were believed to belong to three cells, including the one that carried out the suicide car bombings in Riyadh last week. Another cell has fled Saudi Arabia and the third is at large in the kingdom.
