Two US B-52 bombers fly over disputed East China Sea area
Pentagon spokesman Col. Steven Warren said: "Last night we conducted a training exercise that was long-planned. It involved two aircraft flying from Guam and returning to Guam.” No flight plan was submitted beforehand to China. The two aircraft spent "less than an hour" in China's unilaterally-declared Air Defense Identification Zone (ADIZ) and did not encounter Chinese planes, he said. The move represented a robust show of US support for Japan, which has a longstanding defense treaty with its American ally.
