CETINJE, Montenegro (AP) — Riot police in Montenegro have used tear gas at protesters who fired gunshots in the air and hurled bottles and stones before and during an inauguration of the new head of the Serbian Orthodox Church in the country. Police and media reports say at least seven police officers and several protesters have been injured in the clashes. At least 14 people have been detained. The ceremony Sunday morning in former capital Cetinje has angered opponents of the Serbian church in Montenegro. The country declared independence from neighboring Serbia in 2006. Hundreds of protesters confronted the police in Cetinje on Saturday around a monastery where the inauguration of Metropolitan Joanikije took place.
