Relatives of passengers on Taiwan's TransAsia Airways Flight ATR-72 left Xiamen on Thursday for Taipei, where the plane crashed into a river ten minutes after takeoff, killing at least 31.

The aircraft was carrying 53 passengers and five crew members when it crashed into the Keelong River on Wednesday morning, authorities said. The plane was en route to Kinmen from Taipei.

It has been confirmed that 31 passengers were from the Chinese mainland, and they were on trips organized by two travel agencies from Xiamen City in Fujian Province, the Taiwan tourism authority confirmed.

As of 9:45 a.m. Thursday, 31 had died, 15 sustained injuries, and 12 are still missing. All the missing passengers are tourists from the Chinese mainland.

The Taiwan authorities confirmed that 16 of the 31 mainland passengers had died and three others injured.

The aircraft plunged into the river at 10:55 a.m. Wednesday after its wing clipped a taxi with a man and a woman inside on an elevated freeway.
