AFP: China fired warning flares at PH military planes over West PH Sea

Excerpt
China fired warning flares at Philippine military planes conducting maritime patrols near the artificial islands controlled by China in the West Philippine Sea early this year, the military said Tuesday.
Maj. Gen. Reuben Basiao, deputy chief of staff for intelligence of the Armed Forces of the Philippines (AFP), told lawmakers at a security briefing at the House of Representatives that the flares, which originated from China-held military outposts, were meant to warn Filipino pilots to stay away from the disputed waters.
