Taiwan’s Defense Ministry said that it had detected 44 Chinese military aircraft around the self-ruled island Monday, with 37 crossing what is known as the median line dividing the Taiwan Strait and flying south of the island — just ahead of the U.S. presidential election.

It was the third day in a row that a large number of Chinese military aircraft had been reported in the area, with the Defense Ministry in Taipei saying the earlier instances had been part of exercises that saw them head into the Western Pacific for long-distance flights.

Taiwan's Defense Ministry said it had responded by deploying aircraft, warships and shore-based missile systems.
