Saudi authorities have discovered an arms cache near the capital linked to an al-Qaeda cell dismantled in August, an interior ministry spokesman said on Sunday.
The spokesman, quoted by the SPA state news agency, said the weapons were found in a house after interrogations of 44 people allegedly linked Qaeda whose arrests were announced on Aug. 19.
The arms haul comprised 281 Kalashnikov assault rifles, 250 magazines and 35 cases containing 41,250 rounds of ammunition, the spokesman said.
When 43 Saudis and one foreigner were arrested in August, police also seized around 70 machine-guns, 376 electronic detonation devices and more than 31,000 rounds of ammunition in three caches in a Riyadh residence and desert hideouts.
"These people have links to the original Qaeda organization," interior ministry spokesman General Mansur al-Turki told AFP in August.
"I would describe them like a base. They actually work in the area, recruiting young people, giving young people the ideology of Al-Qaeda and financing terrorism in the kingdom."
Saudi Arabia has battled violent extremists who launched a terror campaign against government and foreign targets in the Kingdom since 2003.
The violence has subsided since 2006 but security concerns were revived when Deputy Interior Minister Prince Mohammed bin Nayef survived an assassination bid inside his palace in August.
The government has arrested hundreds of suspects this year on suspicion of trying to revive militant cells and in February issued a list of 85 wanted militants believed to be abroad.
