Colombian officials say a New Year's Day aerial bombing killed 22 rebels from the Revolutionary Armed Forces of Colombia (FARC).
The death toll reported Saturday is higher than earlier reports.
Authorities say the early Friday morning attack took place in the province of Meta.
Military officials now say ground troops captured eight rebels in the area, including five who were wounded. Initial reports said 13 fighters had been captures.
Meta is a lucrative cocaine-producing region for the rebels.
The FARC has been fighting the Colombian government for four-and-a-half decades and has been designated as a terrorist organization by Colombia, the United States and the European Union.
