Two men were arrested in New York and charged with planning a terror attack on a synagogue.
Ahmed Ferhani, 26, and Mohamed Mamdouh, 20, are immigrants from Algeria and Morocco. They bought guns and a grenade from undercover detectives, police said.
Police Commissioner Raymond Kelly said the men had no known connections to al-Qaeda.
If convicted, they face life in prison without the possibility of parole.
Mr Ferhani planned to disguise himself as a Jewish worshiper, enter the largest synagogue in Manhattan and leave a bomb, police said.
The men were then arrested.
