英语文摘：Brazil helps Colombia release long-time FARC hostage

FARC stressed that those were the last of the unilateral releases which started last year, when six hostages were freed. According to the group, the remaining 21 hostages will only be released in exchange for FARC members who are currently in government custody.

The federal government has been fighting FARC, the largest guerrilla group operating in Colombia, for more than four decades.
