The presence of the warplanes is not connected to tensions on the Korean Peninsula, a Philippine army spokesman said.
"These exercises were planned more than a year ago, well ahead of what is now happening in the region," Major Emmanuel Garcia said.

The war games are being held to test the two allies' defence plans based on the Mutual Defence Treaty, an important link in Washington's chain of security alliances in the Asia-Pacific region. The US has similar military arrangements with South Korea, Japan, Singapore and Australia.
