The US State Department said the risk of a terror attack was particularly high in the Middle East and North Africa between now and the end of August.
It followed a warning from America on Thursday of an al Qaeda plot to attack its embassies in Muslim countries.
Britain changed its travel advice for Saudi Arabia and the Gulf yesterday in the wake of the latest alert, telling diplomats in Arabian capitals to exercise vigilance until the Eid festival, marking the end of the Muslim holy month of Ramadan on Thursday.
In a statement last night, the US State Department officials said American citizens living or travelling overseas should be aware of a potential al-Qaeda attack either in or emanating from the Arabian peninsula.
"Current information suggests that al-Qaeda and affiliated organisations continue to plan terrorist attacks both in the region and beyond, and that they may focus efforts to conduct attacks in the period between now and the end of August," the department said.
The attacks are seen as occurring in or emanating from the Arabian peninsula, according to the statement, and "may involve public transportation systems and other tourist infrastructure." » | Damien McElroy, and Raf Sanchez in Washington | Friday, August 02, 2013
