The Taiwan Ministry of Defense said today, Saturday, that it had detected, during the past 24 hours, 20 aircraft of the Chinese Air Force entering the island's air defense zone.
Aircraft, including fighters and drones, crossed the center line of the Taiwan Strait, which was previously an unofficial barrier between the two sides, but Chinese aircraft have been crossing it over the past year.
Last Saturday, China held a day of drills around Taiwan in an angry response to brief stop-overs this month in the United States by Vice President William Lai.
