Several Chinese warplanes flew close to the median line of the sensitive Taiwan Strait on Tuesday morning, a source briefed on the matter told Reuters, as tensions mounted on news US House of Representatives Speaker Nancy Pelosi was set to visit Taiwan during the day.
The source said several Chinese warships have stayed close to unofficial buffer in the waterway since Monday, adding that Taiwan had dispatched aircraft to monitor the situation.
Taiwan's defense ministry was not immediately able to respond to a request for comment.
