BANGKOK (THE NATION/ASIA NEWS NETWORK) - A minor explosion inside Hua Lamphong Railway Station in Thailand's capital Bangkok on Wednesday (May 11) wounded two people, although the police played it down, calling it an accident.
However, the country's National Security Council (NSC) expressed concern over the blast.
"Although it was a small incident, we didn't overlook it. No matter what caused it, we will have to find out what it was," said General Taweep Netrniyom, secretary-general of the NSC.
The news was reported to the NSC's meeting at Government House by deputy national police chief Sriwarah Rangsitpramkul.
The meeting was chaired by Prime Minister Prayut Chan-o-cha, who ordered police to reveal to the public full details even though the blast was small-scale.
Gen Sriwarah told reporters there was no bomb and no attack.
There was only a bit of gunpowder left inside a bottle that was discarded at a garbage site.
Someone happened to pick up the bottle to use as an ashtray.
The person who threw the bottle away has been found and interrogated.
It was learnt that the incident was not politically motivated, he added.
