Israel has warned it will "settle the score" with those behind a bombing in Bangkok Tuesday believed to be linked to other attacks targeting the Jewish state.

A man carrying grenades blew off his own legs in the blast and wounded four others. A passport at the scene indicated the assailant was Saeid Moradi from Iran.

The bombing came a day after Israel blamed Iran for attacks targeting Israeli embassies in India and the nation of Georgia.

Although Israeli Foreign Ministry spokesman Yigal Palmor said "so far, we haven't found any links between these two cases," he added that "we can't rule out any possibility."

Israeli Defense Minister Ehud Barak said it was an attempted terrorist attack by Iran.

Public Security Minister Yitzhak Aharonovitch implied his country will seek revenge saying.

"We know who carried out the terror attacks, we know who sent them, and Israel will settle the score with them," he told Israel Radio.

Before getting hurt, explosives were detonated by accident in Moradi's home, blowing off the roof.

Moradi fled, and police eventually caught up with him. When they tried to apprehend him, Moradi threw a grenade at the officers that then bounced back and detonated, injuring both his legs.

A second suspect believed to be conspiring with Moradi was arrested at Bangkok's airport.

Israeli police have put the country on high alert following the bombing.
