San Francisco Frontiers - Thai king visits hospital after nursery massacre

The king is expected to meet survivors of Thursday's attack, one of the worst mass killings in Thai history, in a rare public interaction for the monarch, who is officially regarded as a semi-divine figurehead.

Coffins bearing the bodies of the victims -- 24 of them children -- were earlier transported to temples to be handed over to relatives, many of whom had spent the day mourning at the nursery where their children were slain.

Prime Minister Prayut Chan-O-Cha laid flowers at the nursery in rural northeastern Nong Bua Lam Phu province and handed out compensation cheques to grieving families.

At one temple, 10 white and gold coffins, some so small they looked like toy boxes, were loaded into fridges in the evening ahead of the customary three days of mourning before cremation.

A young father, his face a mask of tears, staggered away from other mourners after watching his son's coffin loaded away.

Earlier at the small, low-slung nursery, a line of heartbroken parents placed white roses on the building's steps as the baking sun bore down.

The dead include pregnant teacher Supaporn Pramongmuk, whose husband posted a poignant tribute on Facebook.

"I would like to say thank you for all the support for me and my family. My wife has fulfilled her every duty as a teacher," Seksan Srirach wrote.

"Please be a teacher in heaven, and my child please take care of your mother in heaven."

- Knife the 'main weapon' -

Armed with his own legally purchased 9mm pistol and a knife, former police sergeant Panya Khamrab began his murderous spree at the childcare centre at about 12:30 pm (0530 GMT) on Thursday.

Following the attack, 34-year-old Panya fled the scene in a pickup truck to head home and murder his wife and son before taking his own life, police said, ending the rampage at about 3 pm.

In total, he killed 24 children -- 21 boys and three girls -- and 12 adults.

Pitak Kongtapthai, head of the police investigations unit in the province, said most of the deaths were caused by a combination of knife wounds and gunshots.

Panya joined the police in 2012 and rose to the rank of sergeant but was suspended from the force in January and sacked in June for drug use, National Police Chief Damrongsak Kittiprapat told reporters.

Damrongsak said initial tests found no drugs in Panya's body after the attack, though several locals said Panya was known in the area as a methamphetamine user.

The interior ministry said it would "review and intensify our preventative measures on drugs" in the wake of the attack, including tightening rules on gun ownership.

The police chief said the attacker used his knife as the "main weapon" in the nursery.

He had an argument with his wife hours before the attack, Damrongsak said, but "nothing irregular" was noted when he appeared in court that morning on a drugs possession charge.

Flags on government buildings flew at half-mast on Friday in a gesture of mourning for one of the deadliest days in recent Thai history.

Nanthicha Punchum, acting chief of the nursery, described harrowing scenes as the attacker barged into the building in the rural Na Klang district.

"There were some staff eating lunch outside the nursery and the attacker parked his car and shot four of them dead," she told AFP.

She said the attacker smashed down the door with his leg and then started stabbing the children.

Witness Pranom Innurak described how her sister, now recovering in hospital, was injured.

"He (Panya) was driving a car on his way back home and he rammed into everyone on his way," she told AFP, adding that her sister's daughter was among the dead.

"When my sister got hit, she wasn't that hurt yet. She flew out from her food stall. He then used a knife to attack her."

The tragedy came less than three years after a soldier in the northeastern city of Nakhon Ratchasima gunned down 29 people and wounded scores more in a 17-hour rampage, before he was shot dead by commandos.

And less than a month ago an army officer shot dead two colleagues at a military training base in the capital Bangkok.
