Security concerns are forcing U.S. embassies to temporarily shut down overseas.

FOX News Radio's Kimberly Adams reports from Cairo:

American embassies in Iraq, Jordan, Libya, and here in Egypt are among the announced closures due to the unspecified threat. An attack on the consulate in Benghazi, Libya last year killed the Ambassador and other Americans, and prompted condemnation of the State Department's security protocols. The closure of the embassy here in Cairo comes as the Egyptian Foreign Ministry says it's prepping for a visit from Deputy Secretary of State William Burns.

FOX News Radio's Jared Halpern has more on the travel warning from Washington DC:

The State Department warning suggests Al-Qaeda and affiliated groups could be planning attacks on U.S. interests overseas, sometime this month, particularly in the Middle East and North Africa. The alert cautions Americans traveling abroad to take extra precautions and register with the embassies and consulates in the countries they visit. Lawmakers indicate the embassy threat is linked to Al-Qaeda and focused on the Middle East and Central Asia.

WORLDWIDE August 2, 2013

The Department of State alerts U.S. citizens to the continued potential for terrorist attacks, particularly in the Middle East and North Africa, and possibly occurring in or emanating from the Arabian Peninsula. Current information suggests that al-Qa'ida 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. This Travel Alert expires on August 31, 2013.

Terrorists may elect to use a variety of means and weapons and target both official and private interests. U.S. citizens are reminded of the potential for terrorists to attack public transportation systems and other tourist infrastructure. Terrorists have targeted and attacked subway and rail systems, as well as aviation and maritime services. U.S. citizens should take every precaution to be aware of their surroundings and to adopt appropriate safety measures to protect themselves when traveling. We continue to work closely with other nations on the threat from international terrorism, including from al-Qa'ida.

Information is routinely shared between the U.S. and our key partners in order to disrupt terrorist plotting, identify and take action against potential operatives, and strengthen our defenses against potential threats.
