RIYADH (Reuters) - A total of 5,080 people have been convicted of terrorism crimes in Saudi Arabia, where Al-Qaeda launched a campaign in 2003 to overthrow the Western-allied monarchy, state media reported on Saturday. The reports did not give a time frame for the convictions. Saudi Arabia, with the help of foreign experts, managed to quash an Al-Qaeda campaign from 2003 to 2006 that targeted expatriate housing compounds, embassies and oil facilities. Riyadh destroyed the main Al-Qaeda cells within Saudi Arabia, but some militants slipped into neighbouring Yemen and regrouped to form a Yemen-based regional wing that seeks, among other things, the fall of the US-allied Saudi royal family. The official news agency SPA said the cases of 2,215 people had been transferred to a special terrorism court, quoting a prosecution statement. "This statement gives clear results of the progress regarding sending the detainees to justice," Interior Ministry spokesman Mansour al-Turki told state television. Western rights groups have reported human rights violations in the treatment of alleged militants in Saudi Arabia, a charge the country has rejected.
