A suicide bomber was killed and two other people wounded in a blast near the U.S. consulate in Saudi Arabia's second city of Jeddah early on Monday, state TV said, the first bombing in years to attempt to target foreigners in the kingdom.
The attacker parked his car outside a hospital opposite the consulate at about 2.15am and detonated his device after being approached by two security men, killing him and lightly wounding them, it said, quoting a security spokesman.
Three further blasts rocked the location of the bombing hours later, a witness told Reuters, as police carried out what appeared to be controlled explosions near the site.
A video sent by the witness showed police taking cover behind vehicles and covering their ears before an explosion sounded.
Islamic State has carried out a series of bombing and shooting attacks in Saudi Arabia since mid-2014 that have killed scores of people, mostly members of the Shi'ite Muslim minority and security services.
A decade ago, an al Qaeda campaign focused on Western expatriates in the world's top oil exporter, killing hundreds in attacks on businesses and residential compounds. One 2004 attack hit the U.S. consulate in Jeddah, killing nine.
