U.S. Issues Security Alert for Manila

The United States issued a security alert for the Philippine capital of Manila on Friday, warning its citizens they could be the target of an unspecified attack.

The U.S. embassy in Manila released a statement calling for U.S. citizens to exercise extreme caution and consider canceling American gatherings in the sprawling and chaotic megacity of 15 million people.

"The U.S. Embassy advises American citizens in the Philippines that a threat against American citizens in metropolitan Manila, specifically the Pasay City neighborhood, has been detected by reliable security forces," the statement said.

"This threat remains in effect until October 10, 2012," it said.

The statement said U.S. Ambassador Harry Thomas had ordered stepped-up security for all U.S. government facilities in Manila.

Pasay, a major district in the capital, is home to a heavily guarded U.S. embassy compound called Seafront that contains housing for diplomats, a library, an outpatient clinic and a clubhouse.

The compound is near the Philippine foreign department, as well as a red-light district that attracts foreigners.

U.S. embassy spokeswoman Tina Malone said she was unable to give any more details than were in the alert.

"We felt it important to inform American citizens but we cannot provide specific information at this time," Malone told Agence France Presse.

Philippine Department of Foreign Affairs spokesman Raul Hernandez released a short statement following the alert saying the government was working to ensure the safety of U.S. citizens, but without giving further details.

"Protection of the welfare of its nationals in the Philippines is a duty of the U.S. Embassy in Manila. The DFA sees this emergency message as a fulfillment by the U.S. embassy of this important duty," Hernandez said.

"It is also worth noting that the embassy is coordinating with Philippine law enforcement agencies in assessing, monitoring and, if necessary, responding to this threat."

The U.S. government issued an alert in November 2010 that warned of an attack in Manila, particularly areas frequented by foreigners.

It prompted similar travel advisories by Britain, Australia, Canada, New Zealand and France.

However the attack never materialized, and President Benigno Aquino subsequently criticized the United States and other Western allies for damaging his country's tourism prospects.

The foreign governments eventually lifted their warnings for Manila.

The United States has a general warning about the risks of travel in the Philippines, a former U.S. colony that has for decades battled Islamic separatist rebels and more hardline Muslim militants in the far south of the country.

A longstanding general warning cautions U.S. citizens to avoid areas of the southern island of Mindanao, about 850 kilometers (530 miles) from Manila, because of the threat of kidnappings.

The Abu Sayyaf, a small band of Muslim militants that authorities say was set up in the early 1990s with funds from the al Qaida network, has kidnapped and killed Americans in Mindanao.

About 600 U.S. troops have been rotating through the southern Philippines for a decade to help train local troops in hunting the Abu Sayyaf. However the Americans are barred from taking part in combat.
