About four persons have been killed and others injured when suspected assailants attacked a Hausa/Fulani settlement in Asaba, the Delta state capital on Friday night, around 10 pm.
The suspected killers shot sporadically as people slept and later threw bomb into a Mosque around an area called Cable point.
According to Vanguard, a "brave Hausa man" picked up the bomb and threw it into the river before it could explode.
A source told the newspaper that soldiers and policemen came to their rescue and chased the suspected invaders away.
He said the security agents took the injured persons to the hospital for treatment and deposited the corpse of the deceased at the mortuary.
The Delta state Police Command have heighten security in the state following clashes between The Indigenous People of Biafra (IPOB), led by Mazi Nnamdi Kanu, and the Nigerian Military, who are conducting a military operation in the South East part of the country, codenamed Operation Egwu Eke II (Python Dance).
Operatives have been deployed to areas like Okwe, a settlement for IPOB and other Biafra agitators.
