Terrified passengers fled from a bus after a gunman shot two people onboard in Phuket, Thailand, this morning.

The suspect, estimated to be around 30 years old, was still in a stand-off with police surrounding the vehicle at 11:15 am local time. He is understood to be on the bus alone without any hostages.

He reportedly targeted passengers on the Phuket-Phatthalung bus while it was on Thep Krasattri Road on the popular holiday island at around 6.50 AM.

Police said around 10 people were able to escape after the driver parked the bus. However, one man and a woman were injured and were taken to the hospital for gunshot wounds.

The police temporarily closed the area and were negotiating with the man to surrender peacefully.

The incident took place just a short distance from the Phuket bus station, only a mile from the station. The driver said that the bus left with nine passengers from the station at 6.40 AM.

Some five to 10 minutes after departing, the bus stopped at the traffic light before a gun noise rang out. A woman ran to the front of the bus and told him that she was shot.

He parked the bus on the side before a man was shot.
