At least four people were killed in Colombia on Tuesday as rebel groups detonated bombs near police stations in the city of Cali and the neighbouring Cauca province, according to authorities.

Military and police spokespeople blamed the attacks on the FARC-EMC, a group led by former members of the Revolutionary Armed Forces of Colombia who broke away from the group after it signed a peace deal with the government in 2016. Authorities said the rebels placed bombs in cars and motorcycles that were parked near police stations.

The attacks on the police stations come just days after Miguel Uribe, a conservative presidential candidate, was shot during a rally in Bogota. Authorities say they are investigating who was behind the attack on Uribe, who is in a critical condition in hospital in Bogota.
