Saudi security forces have uncovered a militant hideout filled with bomb-making materials south of the capital Riyadh, the Interior Ministry said on Wednesday.
It said the cache included two tonnes of fertilizer, ammonium nitrate, aluminum powder, potassium nitrate and other chemicals used by suspected al Qaeda militants to make bombs in their two-year wave of attacks against Saudi Arabia.
Security forces who searched the hideout on Tuesday in Kharj, 60 km (40 miles) southeast of Riyadh, also found pipe bombs, acid and electrical equipment, the ministry said in a statement.
The statement came hours after the U.S. embassy in Riyadh warned its citizens in Saudi Arabia that militants were planning fresh strikes in the world's biggest oil exporter. |
