A suicide bomber has been killed and two people wounded in a blast near the US consulate in Saudi Arabia's second city of Jeddah, state TV said.
It is 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.
In a statement, the US consulate said there were no casualties or injuries among its staff, adding that it and the US embassy were in contact with Saudi authorities investigating the incident.
The so-called Islamic State militant group 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 Shia 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 US consulate in Jeddah, killing nine.
