Colombia just carried out a major airstrike against the notorious Gulf Clan, killing eight people, including top figure Haminton Mosquera, in the province of Antioquia.
President Abelardo de la Espriella was elected in June and had campaigned on a crackdown on criminal gangs.
Mosquera suspected in Taraza police murder
The operation targeted Mosquera for his alleged role in violent crimes, including being suspected of having ordered attacks against the security forces, including the murder of a police officer in the municipality of Taraza last year.
The US labeled the Gulf Clan a terrorist group last year.
While many people in high-crime areas support these tough tactics, some critics worry about the aggressive approach.
Still, President de la Espriella says he's determined to win back control from gangs known for drug trafficking and violence.
