NEWS UPDATE: 35 Die as Nigerian Army and Boko Haram Clash

At least 35 people have been killed in two separate gun battles between Nigerian security forces and Islamist sect Boko Haram in northeast Borno state, the army said on Monday.

Boko Haram gunmen on Sunday attacked a police base in Bama, a town close to the Cameroon border that has been frequently hit by violence in recent months.

"Troops have successfully repelled Boko Haram terrorist attacks on a police base in Bama ... on 4 August," said military spokesman Sagir Musa.

Musa said one policeman and 17 members of Boko Haram were killed during the fighting, while two soldiers were injured.

He said four trucks, three motorbikes, dozens of explosive devices, three rocket-propelled grenades, 10 AK47 rifles and over 100 rounds of ammunition were recovered from the Islamists.

Boko Haram members also attacked a military base in the town of Malam Fatori, triggering a gun battle that left two soldiers and 15 of its members dead, Musa said.
