At about 8:30 a.m. local time on the 26th and about 9:30 Beijing time last night, the White House was briefly closed because a plane entered the no fly area over Washington. The Capitol issued a security alert, many roads in downtown Washington were closed, and fighter jets took off urgently.
However, a few minutes later, the law enforcement authorities found out that the plane was "invincible". The White House and Congress immediately lifted the security alert, and no casualties were reported.
