A gun shot from HTMS Chonburi accidentally struck HTMS Khirirat on Thursday, causing a fire and injuring 13 soldiers. Both Thai navy vessels were anchored at Laem Thian Pier, Sattahip Naval Base, in Chon Buri province.
The incident took place at 11.50am when the naval gun shot discharged from the front gun of HTMS Chonburi hit the rear section of HTMS Khirirat.
Firefighters swiftly responded to control the blaze aboard the warship.
The Royal Thai Navy said 13 soldiers were injured, 10 of them in serious conditions. According to media reports, many suffered from smoke inhalation.
An earlier report said three people were injured.
HTMS Chonburi had returned from a firing drill on Wednesday and had returned to the base for repairs, as one of its guns had malfunctioned during the operation, with an unexpended round still in its ported barrel.
