BRUSSELS, Belgium - Belgian police Friday arrested 14 Muslim extremists suspected of planning to free an al-Qaida sympathizer imprisoned for planning a terrorist attack on U.S. air base personnel, officials said.
Security was heightened at airports, subway stations and other public places across the capital, and the U.S. Embassy warned Americans of "a heightened risk of terrorist attack in Brussels" although it had no indication of any American targets.
