Armed gang kidnaps Colombian churchgoers
Army units return a hostage to her family
Gunmen who snatched more than 100 people from a church in a wealthy district of Colombia have been forced to release at least 79 hostages as the army chased them into the mountains.
The army is now trying to drop troops in ahead of the rebel column to cut them off, although it looks as if the rebels will be able to escape under cover of darkness.
Witnesses said armed men entered the Roman Catholic church in the exclusive Ciudad Jardin district of Cali at about 11am (1600GMT) during Mass on Sunday.
The rebels forced the congregation, including women, chidren and a priest, outside and drove them away towards the poor district of Jamoundi, a known ELN stronghold.
Mayor Ricardo Cobo said around 150 people had been attending the service.
Police units and army patrols reportedly engaged in gun battles as they pursued the rebels.
Unconfirmed reports say two rebels and one bodyguard died during the incident.
It is seeking to pressure the Colombian Government into granting a similar "safe haven" to the 42,000 square kilometre demilitarised territory enjoyed by the country's largest guerrilla group, the Revolutionary Armed Forces of Colombia (FARC).
On 12 April, five ELN rebels hijacked a domestic flight and ordered it to fly to a remote jungle airstrip. Twenty five of the 40 or more people on board have now been released.
