Defense Minister Ehud Barak said Tuesday that the attempted bombing in Bangkok proves that Iran and its proxies continue operating with terrorism methods.

"Iran and Hezbollah are relentless terror elements who pose a danger to the stability of the region and the world," Barak said in a statement, during a visit in Singapore.

Earlier on Tuesday, a man thought to be an Iranian national was seriously wounded in Bangkok when a bomb he was carrying exploded and blew his legs off. Shortly before, there had been an explosion in a house the man was renting in the Ekamai area of central Bangkok.

A senior Israeli official said Tuesday that police in Thailand believe that the bombings were a botched terror attack, since the actual explosions did not take place near the Israeli embassy.

Five people were wounded as a result of Tuesday's attack. A taxi driver told Thai television that the Iranian man had thrown a bomb in front of his car before running off, injuring him slightly.

Thitima said police had tried to move in and arrest the man after the blast by the taxi. According to the Bangkok Post, he threw another grenade at the police that hit a tree and bounced back toward him, exploding and causing him to lose both his legs.

"The police have control of the situation. It is thought that the suspect might be storing more explosives inside his house," Thitima said, adding that, according to an initial police report, the man was thought to be Iranian.

Police later said they had apprehended another supsect at Bangkok's main Suvarnabhumi airport, one of two men they were looking for who had been living at the house where the initial blast took place.

"We discovered the injured man's passport. It's an Iranian passport and he entered the country through Phuket and arrived at Suvarnabhumi Airport on the 8th of this month," Police General Bansiri Prapapat told Reuters.

The blasts came a day after a twin bomb attack targeted Israeli embassy staff in India and Georgia. Israel accused arch-enemies Iran and its Lebanese ally Hezbollah of being behind those attacks.

Iran denied involvement in the New Delhi and Tbilisi bombs.

The Bangkok explosions were not near the capital's main area for embassies.
