(Reuters) - The U.S. Consulate in Istanbul said on Tuesday it had canceled consular services for Wednesday because of "information about a possible security threat" against the mission. "We strongly encourage U.S. citizens to maintain a high level of vigilance, be aware of local events, and take the appropriate steps to bolster your personal security," the consulate added in a statement on its website. In Washington, State Department spokesman John Kirby told reporters that routine consular services had been canceled but that limited, urgent services would be provided.
