An Iranian nuclear scientist was killed Tuesday by a remote-controlled bomb planted on a motorcycle parked outside his home, state news outlets reported. Iran's Foreign Ministry blamed the attack on the United States and Israel, without giving details, state broadcaster IRIB said.

Masoud Ali Mohammadi was killed as he left his house in the north Tehran neighborhood of Qetariyeh. State television showed images of crying people and houses with broken windows as a burned-out motorcycle was taken away by security forces.

The rare bomb attack comes amid tensions between the government and a vocal grass-roots opposition movement and international pressure over Iran's controversial nuclear program, which Tehran says is aimed only at energy production and other peaceful activities but the United States and its allies believe is focused on creating nuclear weapons.

Tehran's chief prosecutor, Abbas Jafari Dolatabadi, said Mohammadi was a nuclear scientist, but according to the state news agency IRNA, he was not an employee of the Iranian Atomic Energy Organization, which controls the country's nuclear program.

"Some rumors regarding the employment of Dr. Masoud Ali-Mohammadi by the Iranian Atomic Energy Organization are strongly denied," the organization said in a condolence message carried by IRNA on Tuesday.

It sounds like this guy's specialty - particle physics - would not have necessarily made him an employee of the nuclear bomb program. More likely, it was a political hit due to one opposition group claiming he wrote a letter praising Mousiavi - whose nephew was also assassinated a couple of weeks ago.

Terror from the government? It's what we've come to expect.
