Burundi coup bid: Some coup leaders 'arrested'.

Tens of thousands of people have fled since the unrest began last month

Three renegade generals who launched a failed coup against Burundi's president have been arrested, reports say.

But their leader, Gen Godefroid Niyombare, is still "on the run", according to a presidential spokesman.

Gen Niyombare, who launched the coup attempt on Wednesday, told the AFP news agency: "I hope they won't kill us."

President Pierre Nkurunziza has tweeted he is back home. He was in Tanzania when the coup attempt against his bid to seek a third term was launched.

Five soldiers were killed in clashes in the capital, Bujumbura, on Thursday.

"We have decided to surrender," Gen Niyombare told AFP. He added that troops loyal to the president were approaching him.

Another of the renegade generals, Gen Cyrille Ndayirukiye, admitted earlier that the attempt to overthrow the president had failed.
