PRETORIA - Heavy gunfire's been heard in the capital of Congo, Brazzaville, where a government official says police are battling militia fighters.

The fighting comes weeks after President Denis Sassou Nguesso won an election after a constitutional referendum removed age and term limits that would have barred the 72-year-old from running.

The intermittent gunfire was heard in the capital this morning as police battled militia known as the Ninjas.

These were one of the main anti-government forces in the 1998-99 civil war.

They signed a ceasefire agreement but took up arms again in the early 2000s to demand a role in military and political decisions.

A peace deal was signed in 2003 between the militia and government.

In the run-up to last October's referendum, 18 people died in clashes between anti-government protesters and security forces.
