LOS ANGELES, CA (Catholic Online) - Tehran accused Israel and the United States of assassinating four Iranian scientists, as of 2010, to sabotage their nuclear program, which the West suspects is hiding Iran's attempt to develop nuclear weapons. While declining to comment on the killings, Israel thinks Iran's nuclear program is an existential threat and has threatened Tehran with military force. Washington has denied any U.S. role in the killings.

Majid Jamali Fashi, 24, was hanged at Tehran's Evin Prison after being sentenced to death last year for the murder of Massoud Ali-Mohammadi. According to Iran's state news agency, Fashi confessed to the crime. Ali-Mohammadi was killed in January 2010, when a remote-controlled bomb went off outside his home in Tehran.

Last month, Iranian intelligence said that they had arrested 15 people that they called a "major terror and sabotage network with links to the Zionist regime." The group plotted to assassinate an Iranian scientist in February.

Iran denies Western accusations of it seeking to develop a nuclear weapons capability; however Israel said it would attack Iran if they think that it is the only way to stop them from obtaining nuclear arms.

William Hague, British Foreign Secretary, warned the European Union would impose stricter sanctions on Iran if it fails to take steps to allay international concerns over its nuclear program.
