A leading commander of the Farc rebels in Colombia has surrendered to the authorities, officials say.

Eldaneyis Mosquera, better known as Karina, was blamed for a string of murders, abductions, and for extortion in the north-western Antioquia region.

Her surrender is a coup for President Alvaro Uribe who made her a priority target for the security forces in 2002, the BBC’s Jeremy McDermott says.

Farc has been fighting to overthrow the government for more than 40 years.

$800,000 reward

Karina has a fiercesome reputation in Antioquia, and many businessmen and ranchers have suffered extortion, kidnapping and murder at her hands, our correspondent says.

None doubt her fighting prowess and she has the wounds to prove it: she has lost an eye in combat, has scars across her face and a bullet wound on one of her arms.

In 2002, a reward of more than $800,000 (£409,000) was placed on her head.

Karina was an example for the women in the rebel army, that make up more than a third of Farc ranks, our correspondent says.

Her immediate boss Ivan Rios, a member of the Farc ruling seven-man secretariat, was murdered in March by one of his bodyguards.

The bodyguard chopped off Rios’s hand in order to prove to the authorities he had killed the commander and so collected a reward in excess of $1m (£510,000)

Since then Karina had been in sole command of the Farc division in the Antioquia.

Farc – the Revolutionary Armed Forces of Colombia – has been fighting to overthrow the Colombian government for more than 40 years.
