According to an Air Force statement, the two Chinese fighter jets, a Shenyang J-11 and a Chengdu J-10, briefly crossed the line to Taiwan's side of the median line at around 9 a.m.
They then retreated to the western side of the line after Taiwanese patrol planes issued radio warnings and with air defense missiles activated on the ground.
The incident came just one day after United States Secretary of Health and Human Services (HHS) Alex Azar and his delegation arrived for a visit Sunday. He is the first U.S. Cabinet official to visit Taiwan since 2014. [FULL STORY]
