Two Chinese fighters have carried out an "unsafe" intercept of a US military aircraft over the South China Sea, the Pentagon says.
The incident happened in international airspace on 17 May as the US maritime reconnaissance aircraft carried out a routine patrol in the area, it added.
Tensions in the region have increased recently, with China and the US trading accusations over military activity.
