Earlier in the day, police used tear gas and clubs to clear away dozens of protesters left outside the church and detained three people. Skirmishing outside the building continued sporadically.

Demonstrators and police clashed dozens of times during the day, often violently, and protesters burned a van belonging to a television station as well as nearby phone booths.

The Red Cross (searchsaid it treated 25 people, including several children, who were suffering from the effects of tear gas or had been injured by rocks thrown by protesters.

"This isn't the way to talk to the government," Saca said of the protest.
