Ugandan opposition leader Kizza Besigye has appeared in court to face charges of treason, as protests sparked by his arrest continued for a second straight day in the capital, Kampala.

A magistrate Tuesday ordered Mr. Besigye's case to be transferred to the High Court.  The treason charge is punishable by death, and the lower court cannot try death penalty cases.

Outside the courtroom, security forces used live ammunition and teargas to disperse hundreds of angry opposition supporters, some of whom ransacked shops and burned tires. One person was shot and killed. Dozens were arrested.

Mr. Besigye and 22 others were arrested Monday, accused of planning to topple the government.  He also faces a separate rape charge.  Mr. Besigye returned to Uganda last month after four years in exile. 

He lost the 2001 presidential election to incumbent Yoweri Museveni, and was expected to be the president's toughest challenger in next year's election.
