ADDIS ABABA, Ethiopia — As midday prayers came to an end at the Grand Anwar mosque in Ethiopia's capital, worshippers continued to what has become a regular second act on Fridays — shouting anti-government slogans.

The demonstrations this Friday did not turn violent. But tensions are rising between the government in this mostly Christian country and Muslim worshippers.

Last Monday, federal prosecutors charged a group of 29 Muslims with terrorism and working to establish an Islamic republic.

On Monday, a court is scheduled to rule in the case of 11 people charged with being members of al-Qaida.

In July, hundreds were arrested after a scuffle in a mosque that injured many.

Ethiopia's former leader, Meles Zenawi, who died in August, expressed concern about rising Islamist fundamentalism.
