New Delhi: Six foreign pilgrims were hurt when a suicide bomber targeting Islam's holiest site of Mecca blew himself up on Friday. The Interior Ministry said, security forces have prevented the imminent attack on the Grand Mosque in Mecca. It said, five security men were also slightly hurt.

The suspect refused to comply with demands to surrender, opened fire on security forces and then killed himself. Interior Ministry spokesman said, four injured have already been released from the hospital.

It said, five people, including one woman, suspected of involvement in the plot were arrested. The Saudi Interior Ministry said that three groups, two based in Mecca and one in Jeddah, planned the attack. Similar incidents occured last year near the end of Ramazan in the Saudi city of Medina where four security officers died in an explosion close to Islam's second holiest site, the Prophet's Mosque.
