Police in Saudi Arabia have arrested 40 foreigners on charges of attending a Christian service in the Muslim country's capital, Riyadh. Authorities say the arrests took place Friday after police raided a building where the foreigners were attending a church service run by a Pakistani man. In Saudi Arabia it is illegal to promote religions other than Islam, and those who do so risk prison. Saudi Arabia has come under repeated criticism from the United States and human rights groups for its intolerance of other faiths. In February, the State Department sharply criticized Saudi Arabia for violating religious freedom. In its annual report, the State Department said religious freedom does not exist in the country where non-Muslims face serious discrimination.
