Pakistani security personnel stand guard outside the U.S. consulate in Lahore on Aug. 5, 2013.
All but emergency personnel at the U.S. Consulate in Lahore, Pakistan, have been evacuated to the embassy in Islamabad in response to a specific terror threat, a senior State Department official confirmed to NBC News Thursday night.
The State Department also advised U.S. citizens against traveling to Pakistan.
The threat that prompted the evacuation is different from the threat that temporarily shuttered 19 U.S. diplomatic posts in the last week, the official said.
"We are undertaking this drawdown due to concerns about credible threat information specific to the U.S. Consulate in Lahore," the official said. "As such, the department is taking appropriate steps to protect our employees and others who may be visiting our facilities."
The official said an updated travel alert was issued following the evacuation of non-emergency personnel. The alert advises U.S. citizens to "defer all non-essential travel to Pakistan."
"The presence of several foreign and indigenous terrorist groups poses a potential danger to U.S. citizens throughout Pakistan," the alert says. "Across the country, terrorist attacks frequently occur against civilian, government, and foreing targets."
The alert goes on to say that the threat information "indicates terrorist groups continue to seek opportunities to attack locations where U.S. citizens and Westerners are known to congregate or visit."
