A Catholic leader in Congo says gunmen have killed a parish priest after a Mass in Congo's eastern region.

The Rev. Emmanuel Kapitula in Kitchanga said armed men entered a room in Masisi where the priest, Etienne Nsengiunva, was eating with others on Sunday and shot him dead.

Kapitula called on the government to protect people and to investigate Nsengiunva's slaying.

The killing comes a week after another priest was kidnapped after celebrating Easter Sunday Mass. He was released Thursday.

Roman Catholic churches and activists have led nationwide demonstrations this year against Congolese President Joseph Kabila's extended rule.

The Catholic Church oversaw the signing of an accord a year ago that set a date for a new election in the mineral-rich country, but the election repeatedly has been postponed.
