Saudi Arabia finds Riyadh explosives depot, arrests 5 - report

RIYADH (AFX) - Saudi authorities said they discovered an explosives depot in Riyadh five days ago and arrested five suspects linked to February's failed attack on an oil processing plant.

'The investigation led us to one of their dens... in the (eastern) Al-Sulai neighborood in Riyadh and we found 123 explosives bags weighing more than a ton and a half,' an interior ministry official was quoted by the state-owned SPA news agency as saying.

He said the five suspects were arrested in the aftermath of clashes in another Riyadh neighborhood in late February that killed another five linked to the attempted attack on the Abqaiq processing plant in the oil-rich Eastern Province.

The Feb 24 attempt on Abqaiq, which left two security guards dead, was later claimed by Al-Qaeda in a purported Internet statement.
