The Philippines has placed all its commercial airports on heightened alert after an anonymous warning that bombs could go off on planes headed out of Manila, including to several tourist hotspots, its civil aviation authority said Friday.
"Immediate enhanced security measures" were being implemented at 42 commercial airports across the country, the Civil Aviation Authority of the Philippines (CAAP) said in a media advisory, adding the warnings were being verified.
The warning had been sent by email to air traffic services about a threat to flights out of the capital Manila headed to Davao, Bicol and the popular tourist regions of Palawan and Cebu.
