Riyadh: Four men were killed Sunday as they attacked a Saudi security services base in a town north of Riyadh, pro-government media reported.
The attack targeted state security forces in the town of Zulfi, 260 kilometres (160 miles) north of the capital, London-based Arabic daily Asharq al-Awsat reported.
It said the attackers had rammed a vehicle into a security barrier around the base in an attempt to gain entry.
Two gunmen then stepped out of the vehicle and opened fire, sparking a gun battle with police, who killed them, the paper reported.
A third attempted to flee but was also gunned down, while a fourth died as he tried to set off an explosive belt.
It did not mention any casualties among security personnel.
The Saudi-owned satellite channel Al-Arabiya also reported four people died during an attack, but did not give details.
Two men armed with explosives were killed April 7 and two others arrested as they attacked a security checkpoint in a predominantly Shiite region in eastern Saudi Arabia, which has seen years of demonstrations against the Sunni royal family.
Sunday’s attack took place in a majority Sunni region.
An estimated 10-15 percent of the ultra-conservative kingdom’s 32 million population are Shiite, although no official figures exist.
