Two held in 'US envoy death plot'

Two people have been arrested for conspiring to kill the US ambassador to Saudi Arabia, US officials say.

A federal criminal complaint in New York says the two are also charged with conspiring to use a weapon of mass destruction.

It says the ambassador was in the United States when the death plot was supposed to occur.

The suspects are identified as Manssor Arbabsiar and Gholam Shakuri.

According to a criminal complaint, Arbabsiar is a naturalised US citizen who holds both a US and an Iranian passport.
