Informants who aided the rescue of four members of the Colombian security forces from rebels will share a $1.2m (£800,000) reward, the army has said.

The three police officers and a soldier had been held captive by the Farc guerrillas for almost a decade.

They were rescued on Sunday in an army raid on a rebel camp in the jungle in southern Colombia.

The army did not say how many informants were involved, but said one was a rebel deserter.
