Thailand's Prime Minister Prayuth Chan-ocha has claimed that authorities had seen "some suspects" in security-camera footage of the Bangkok bombing that killed at least 21 people and left 140 injured.
According to the New York Times, Prayuth promised to track down the perpetrators of what he called the country's worst attack in history.
The prime minister also said that the police are investigating a suspect seen on security footage at the shrine.
The attack targeted a major tourist attraction, the Erawan Hindu shrine.
