Mass arrests in Nigeria's Biafra protest

At least 100 people have been arrested in south-eastern Nigeria after a march supporting independence for the former breakaway state of Biafra.

Members of the Biafran Zionist Movement (BZM) raised the Biafran flag and then marched through the streets of the region's main town, Enugu.

One of the group's leaders told the BBC that 500 people had been detained but a police spokesman put the number at 101.

More than one million people died during the 1967-70 Biafran conflict.

Most of the deaths were caused by famine.

The BZM first gathered on Sunday to mark the birthday.

Meanwhile, at least 25 suspected gunmen were arrested in connection with the killing of a policeman on duty in Kano State in north western Nigeria, local police said Monday.

State Commissioner of Police Ibrahim Idris said the gunmen were nabbed on Sunday after launching attacks in the Kano metropolis.

"The gunmen attacked and killed a policeman at Unguwa Uku area of Kano State on Saturday, while he was on duty," said the police chief, adding that security operatives had been trailing gang for other crimes committed within the state.

Members of the gang had stormed the police officer's duty post on motorcycles early Saturday and opened fire on him, Idris explained.  "The gunmen shot severally in the air after killing the police officer, before fleeing the area," he said further.

According to him, security operatives have continued to comb the area to apprehend other criminals. Arrest of the 25 assailants in Nigeria's north western state of Kano occurred barely 24 hours after authorities of the Nigerian police announced the killing of 14 gunmen in Rivers State located in the oil-rich region of the west African country. Kano State is among the northern cities often witnessing wave of attacks that have recently plagued the northern and central parts of Nigeria.
