The Colombian rebel group FARC will halt military operations at midnight as a sign of good will for peace talks with the Colombian government, the group said Monday.

The halt will last until January 20, FARC representative Ivan Marquez said.

The government has not said whether it will take part in a cease-fire during the talks.

Negotiations are aimed at ending the longest-running insurgency in Latin America. The leftist FARC, or Revolutionary Armed Forces of Colombia, has been at war with the government since the 1960s.
