Unidentified hostages stand inside a bank branch in Altagracia de Orituco in the central state of Guarico, some 350 km (217 miles) south from Caracas, January 29, 2008. Venezuelan bank robbers with pistols and a hand-grenade agreed to give up most of their hostages on Tuesday and drive away from a two-day-old siege in an ambulance with a few captives, officials said.
