Colombian rebels lobbed gas canisters packed with explosives at police barracks in San Miguel, killing eight officers near the border with Ecuador. A firefight ensued in the jungle, and two rebels were killed. The region, Putumayo, is a big producer of cocaine, and a stronghold for the Revolutionary Armed Forces of Colombia, known as FARC. FARC rebels have been launching attacks since President Juan Manuel Santos took office, likely in a bid to get the government to hold peace talks with the group. But Santos has sworn to eliminate the “terrorist threat.” A separate FARC ambush killed 14 police Wednesday.
