BANGKOK - A Thai soldier killed at least 17 people in a shooting rampage on Saturday in the city of Nakhon Ratchasima in the northeast of Thailand and remains at large, police said.

Another 21 people were wounded in the shooting, police spokesman Kissana Phathanacharoen said in a message sent to reporters.

Police identified the suspect as Jakrapanth Thomma. He had posted on his Facebook page earlier in the day that “Death is inevitable for everyone.” He also posted a picture of what appeared to be his hand holding a gun.

At one point after the shooting had begun, the suspect posted “Should I give up?” before his account became inaccessible.

The soldier opened fire at different locations in the city, which is more than 250 kilometers from capital Bangkok, police spokesman Kissana Phathanacharoen said in a message sent to reporters.

The shooter remained close to a shopping mall and had not yet been apprehended, the police said.

“We don’t know why he did this. It appears he went mad,” said defense ministry spokesman Kongcheep Tantrawanit.

Local media showed footage of the soldier getting out of a car in front of a shopping mall and firing a series of shots, sending people running. Gunshots could be heard on the video.

One video from a bystander showed a man slumped at the wheel of a car in a pool of blood. It was unclear if he was among the dead.

A woman interviewed by Thailand’s Channel One television said she had heard gunshots when she was at the shopping mall and hid in a clothing store with other people before escaping.

The shooter had initially gone to a house in the city and shot two people dead, before going to the weapons store on an army base and taking a new gun, local police said.

He also shot at people on the army base, they said.

Thai army chief Apirat Kongsompong issued an order for local army commanders to rush to the scene and investigate.

Prime Minister Prayuth Chan-ocha expressed condolences to the families of those killed, a government spokeswoman said.

Facebook said on Saturday it had removed the account of the man suspected of a mass shooting in northeast Thailand and would remove any content related to the attack that violated its policies.

The man identified by police as the suspect had appeared to post messages on Facebook before and during the shooting. Police said he was still at large.

"Our hearts go out to the victims, their families and the community affected by this tragedy in Thailand. There is no place on Facebook for people who commit this kind of atrocity, nor do we allow people to praise or support this attack," a Facebook representative said in a statement.

"We have removed the gunman's accounts from our services and will work around the clock to remove any violating content related to this attack as soon as we become aware of it."
