Anti-government Muslims in Ethiopia are calling for mass demonstrations to be held on the religious day of Eid al-Fitr later this week to protest the arrests of 28 people on terror charges.

The calls follow a weekend of violence in which three people were killed when security forces clashed with what police labeled Muslim "extremists."

Hundreds of people held rallies near mosques in the capital, Addis Ababa, and some regional towns on Friday and Saturday.

Police in the Oromia region said some protesters fired guns at police. The state news agency said all three killed were police officers and that 11 people were injured during the hours-long unrest. Muslim leaders, however, said that police stormed a peaceful protest and killed about a dozen people.
