Several bursts of automatic gunfire were heard early on Sunday (February 9) from a shopping mall in northeastern Thailand where police said a soldier was holed up after killing at least 20 people, Reuters witnesses said.
Security forces stormed into the mall earlier to bring out hundreds of people who were trapped inside.
The soldier opened fire in several places, first at a house and then at an army base, before heading to the shopping mall in Nakhon Ratchasima, which is about 250 km (155 miles) from the capital Bangkok, police said.
The health ministry said 31 people had been wounded and 10 were in a critical condition.
