US embassy in Kenya on Saturday warned of the threat of an imminent attack in Mombasa, a top tourist destination. The warning comes with Kenyan police arresting two Iranians on suspicion of planning bomb attacks. A statement issued by US embassy in Nairobi also said all US government travel to Mombasa is suspended until the first of next month.

France's embassy in Nairobi also warned its citizens to be "extremely vigilant" in Mombasa and the surrounding area.
Kenyan police officials immediately made statements calling for calm.
