BANGKOK (AP) — A train crashed into a public bus on Saturday in Thailand’s capital, Bangkok, killing at least eight people.

Thai news reported the crash happened in the late afternoon near an airport railway station in the central area. The city’s emergency services, Erawan Medical Center, said at least eight people were killed and more than 20 others were injured.

Footage of the moment of the crash shared on social media showed a line of vehicles had stopped at a railway crossing when a cargo train struck an orange bus. The impact also dragged several nearby vehicles along the tracks before the bus was engulfed in flames. Several motorcycles and their riders were also seen being thrown onto the road after the collision.

Later videos showed a group of rescuers entering the charred bus after the flames were brought under control.

Deputy Transport Minister Siripong Angkasakulkiat told reporters at the crash site that all the bodies were found on the bus. He said it was still unclear how many people were on board.

When asked about reports that the bus had stopped on the railway tracks and that the barriers, used to keep motorists away from the tracks when the trains are passing, may not have lowered properly, Siripong said the matter still needs to be investigated.

Kittipong Raksa said he parked his car near the train tracks when he heard the signal indicating the train was about to pass.

“I heard a thud and then another. I heard something hitting my car,” said Kittipong. “Then I saw the train pass, dragging the bus with it.” He said after the collision, he found someone caught under his car, with a broken leg.

Kittipong said he did not see the barriers being lowered.
