Photos Show Alleged Iran Bombs Hidden In $27 Radio (VIDEO)

An alleged Iranian hit squad used $27 portable radios to hide at least five bombs that Israeli and American authorities say they intended to use against Israeli targets in Bangkok, Thailand.

Forensic photographs obtained exclusively by ABC News show an undetonated explosive device that was designed to be a part of a failed bomb plot in Thailand. Three Iranian suspects were arrested last week for their alleged involvement in the plot which fell apart when a similar device apparently exploded in an accident at the house where the Iranians were staying.

An alleged Iranian hit squad used $27 portable radios to hide at least five bombs that Israeli and American authorities say they intended to use against Israeli targets in Bangkok, Thailand.

Exclusive photos of one undetonated bomb, obtained by ABC News, show the inside of the radio packed with tiny ball bearings and six magnets. Bomb experts say the magnets indicate the bomb was designed to be stuck to the side of a vehicle.

A surveillance photo of one of the alleged hit squad members, identified as an Iranian national named Saeid Moradi, shows him holding a radio in each hand.

The photographs show the bomb used what appears to be a hand grenade firing mechanism and was packed with military-grade explosives and ball-bearings generally designed to maximize casualties. Six magnets also appear to be attached, allowing an attacker to physically stick the explosive to its intended target.

According to authorities, a bomb exploded in the Bangkok house where Moradi and two other Iranians had been staying. After the blast, Moradi attempted to hail a cab. When the driver refused to pick him up, he allegedly threw a bomb, injuring four bystanders.

When police approached, Moradi allegedly threw another bomb, but lost both of his legs when it bounced back and exploded near him, according to Thai authorities. He was arrested following the incident and remains in custody in Thailand.

After the attack, police say they discovered two unexploded bombs in the house where Moradi and the other Iranians had been staying, including the one shown in the photos.

In surveillance photographs from just before the incident, one of the Iranian suspects is seen apparently carrying two of the radios -- believed to be concealing explosives -- in either hand.

The authorities in Bangkok say they recovered more than a pound of white military explosive from one unexploded bomb that they said was to be detonated with an M26 hand grenade fuse. The photos show a pin that when pulled, authorities said, would trigger an explosion about four and a half seconds after it was pulled.

Israeli authorities and U.S. bomb experts say the bomb in the photos is strikingly similar to those used in other attacks last week in the republic of Georgia and India. "While there are small differences," said one U.S. expert, "they appear to be factory made."

Multiple authorities told ABC News the devices were either slipped through airport security or smuggled in a diplomatic pouch.



A magnetic bomb was discovered attached to the car of an Israeli diplomat in Tbilisi, Georgia and a similar device was believed responsible for the attack in New Delhi, which injured the wife of an Israeli diplomat, her driver and two passing motorists.

Iran has denied any connection with the arrests in Bangkok or to the other attacks.
