WASHINGTON — The United States issued a global travel alert Friday, citing an al-Qaida threat that also caused the State Department to close its embassies Sunday around the Muslim world.
The State Department warned American citizens of the potential for terrorism particularly in the Middle East and North Africa, with a possible attack occurring or coming from the Arabian Peninsula.
"Current information suggests that al-Qaida and affiliated organizations 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 statement said.
The alert was posted a day after the U.S. announced it would close diplomatic facilities on Sunday because of an unspecified threat. Spokeswoman Marie Harf said the department acted out of an "abundance of caution" and that some missions may stay closed for longer than a day. Sunday is a business day in Muslim countries.
The State Department issued a major warning last year informing American diplomatic facilities across the Muslim world about potential violence connected to the anniversary of the Sept. 11 terrorist attacks.
Dozens of American installations were besieged by protests over an anti-Islam video made by an American resident.
In Benghazi, Libya, the U.S. ambassador and three other Americans were killed when militants assaulted a diplomatic post, but the administration no longer says that attack was related to the demonstrations.
Friday's alert warned that al-Qaida or its allies may target U.S. government or private American interests. It cited dangers involved with public transportation systems and other prime sites for tourists, noting that previous terrorist attacks have centered on subway and rail networks as well as airplanes and boats.
