News:::Islamic State-linked militants 'seize Nigeria's Baga town'

Update::

Militants linked to the Islamic State (IS) group have hoisted their flag in a Nigerian town after seizing control of it, three residents have told the BBC.

Hundreds of people have fled the fishing town of Baga after the militants overran it on Wednesday night, the residents said.

The militants seized weapons from a military base, and torched a naval base on the shores of Lake Chad, they said.

The military denied Baga had fallen, saying the attack had been repelled.

But PRNigeria, an agency well-connected with the military, quoted an intelligence officer as saying that troops had made a "tactical withdrawal" from their base after coming under attack.
