More details have been released on last week’s hijack attempt.

Chinese authorities allege a 19 year old Muslim woman boarded a Beijing bound flight from Xinjiang and planned to blow up the plane.

She took two softdrink cans filled with petrol onto the flight, which she allegedly planned to use as a petrol bomb.

“This (attack) had been under preparation for a long period, the planning was very detailed and was closely linked to terrorist activities,” the Global Times said, citing an unnamed official with knowledge of the case.
