The Gambia's President Yayha Jammeh has returned to the country after a reported coup attempt, sources say.

Heavy gunfire was heard near the presidential palace in Banjul on Tuesday but officials say the military takeover was thwarted.

Details remain sketchy but Mr Jammeh, 49, said there had been an attempted invasion from neighbouring Senegal.

He seized power in the tiny West African nation in 1994, and is accused of not tolerating any opposition.

An official told the BBC that everything had now returned to normal.

A pro-opposition radio station says most businesses are closed, while the market in the biggest town, Serekunda, is deserted.

The pro-opposition Freedom newspaper reports that four people were killed, including the alleged ringleader Lamin Sanneh, a former head of the presidential guards, but this has not been confirmed.

Mr Jammeh was said to have been in either France or Dubai during Tuesday's unrest but different sources agree he has now returned.
