An assailant stabbed three clerics at a Shiite site in Iran on Tuesday, according to Iranian state-run media.
The attack resulted in killing one and injuring two. He was later arrested by security forces.
The motive for the attack remained unclear.
“One cleric died almost instantly after being stabbed at the Imam Reza shrine, while the two others were hospitalized,” Iran’s state-run IRNA news agency reported.
IRNA news agency posted a video of police arresting the assailant.
The Imam Reza shrine in Mashhad is the largest complex housing a tomb in Iran and its most visited. The shrine draws about 20 million people a year, mostly Iranians and pilgrims from neighboring nations like Iraq and Pakistan.
