BEIJING (AP) — China says six Filipinos landed on a tiny outcropping that both countries claim in the South China Sea, days after photos emerged of Chinese coast guard officers displaying a Chinese flag on the same group of sandbars.

The competing claims are reigniting tensions in the South China Sea and coincide with joint military drills between the U.S. and the Philippines.

The standoff over Sandy Cay, which lies close to military outposts built by both Beijing and Manila, was the latest between the two nations.
