The US has issued a global travel alert after allegedly receiving an unspecified al-Qaeda threat.
The state department in a statement said there was particularly strong potential for attacks in the Middle East and North Africa and recommended that US citizens be vigilant while travelling abroad.
The statement said, "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," warning of "the potential for terrorists to attack public transportation systems and other tourist infrastructure".
