Bangkok (VNA) – No Vietnamese citizens were injured at the bomb blast at a military-run hospital in Bangkok, Thailand, on May 22.

Nguyen Hai Ngoc, First Secretary of the Vietnamese Embassy in Thailand, said the embassy will keep contact with Thailand’s competent agencies to update the situation.

The bomb explosion at the army's Phramongkutklao hospital in Rajthevi district injured 25 people. Many of them are soldiers and retirees, and most had cuts caused by broken glass.

Initial investigation showed that the explosion was carried out by the same network behind the blasts near the Government Lottery Office on April 5 and in front of the National Theatre on May 15, local authorities said on May 23.

Army Commander-in-Chief General Sitthisart Chalermchai said the three attacks used the same kind of explosives.

At the hospital explosion, the bomb was hidden in a vase in a room named “Wongsuwan” in honour of Thai Defence Minister General Prawit Wongsuwan.

Authorities said that the country tightened security in Bangkok on May 23, a day after the bomb blast.

Police and soldiers have been deployed to several key locations in the capital, especially crowded areas, to prevent similar incident, Deputy Defence Minister Udomdej Sitabutr said at a Cabinet meeting.

Deputy police spokesman Krisana Pattanacharoen said investigators are seeking for more proof and collecting statements of witnesses.

Following the explosion, some embassies in Thailand like the UK, Canada and Australia urged their citizens to be on alert to strictly follow the advice of local authorities.

In an effort to ease the concern of the international community, Thai Foreign Minister Don Pramudwinai stressed the Government’s commitment to ensuring safety in the country and called on Thai citizens to provide relevant information for authorities. - VNA
