A truck crashed into a market in South Korea on Thursday, killing two people and injuring 18 others, officials said.

Axar.az informs The pickup plowed through Jeil Market in Bucheon just southwest of Seoul at around 11 a.m., according to police, adding that the driver was detained at the scene.

"The driver claims it was sudden unintended acceleration, but it is hard to verify based on CCTV footage of the moving vehicle," Park Geum-cheon, an official from Bucheon Fire Station, told reporters.

Park said the driver, in his 60s, was not under the influence and crashed into people on the market's pathways, not into the stores.

The truck first moved 28 meters in reverse before lurching 150 m forward, he added.

The two killed were both women in their 70s. The injured included three with impaired consciousness and six classified as emergency patients.
