Colombia's FARC guerrillas said Friday they are suspending the unilateral ceasefire they declared in December over a government air strike that killed 26 rebels.

"FARC suspend unilateral ceasefire," said a blog post by the rebel delegation at peace talks to end the five-decade conflict. It blamed the "incoherence" of President Juan Manuel Santos's government in ordering the strike, which came after a rebel ambush last month.
