LONDON, Aug. 6 (UPI) -- U.K. citizens are advised against all but essential travel in the Philippines after an attack at an airport that killed two people, the U.K. government said.
London issued a travel advisory Friday for the Philippines after an explosion at Zamboanga airport killed two people Thursday and left another 24 injured.
"There is ongoing terrorist and insurgent activity in the Philippines," the warning from the British Foreign and Commonwealth Office read. "We advise against all travel to southwest Mindanao and the Sulu archipelago, and against all but essential travel to the remainder of Mindanao".
One of those killed in the Thursday blast was thought to be a suicide bomber. China's official Xinhua news agency said security forces in the Philippines are on high alert following the attack.
The attack happened ahead of the planned visit by Henry Thomas, the U.S. envoy to the Philippines, who was scheduled to discuss various U.S.-backed efforts in Zamboanga. Thomas canceled the trip, Xinhua reported. UPI
