Police say an Iranian man using a fake Israeli passport was arrested outside the Israeli embassy in Nepal and is being questioned.

Kesh Bahadur Shahi of Nepal's Central Investigation Bureau said Wednesday the man identified only as Mohsin Khosravian is being held in a detention center in Katmandu.

Police said the man was arrested last week after Israeli embassy officials told them that a suspicious man appeared to be scouting the embassy in the upscale Lazimpat neighborhood in Katmandu.

Police said they could not give any more details as the case is a sensitive diplomatic issue and still being investigated.
