At least two people were killed on Tuesday after a string of bomb explosions targeted police posts in the southwestern Colombian city of Cali, officials said.

Spanish news agency EFE reported that at least 36 people were injured in the explosions.

While it remains unclear who carried out the apparently coordinated attacks, guerrilla groups that split from the once-powerful FARC militia are known to be active in the area.

What do we know about the attacks in Cali?

The blasts occurred in the neighborhoods of Melendez, Manuela Beltran and Los Mangos. One of the bombs is believed to have been planted on a motorcycle, according to officials.

Cali Mayor Alejandro Eder stated on social media platform X that emergency services were responding. "Our security forces are on the scene and health teams are on alert in case of further incidents," he said.

Footage from the attacks showed several people lying injured in the streets while bystanders and police attempted to assist them.

The bombings came just days after the attempted assassination of a presidential candidate in Bogota, a brazen attack that has put the country on edge. Conservative Senator Miguel Uribe Turbay, 39, was shot twice in the head at close range by a 15-year-old alleged attacker while campaigning Saturday in Bogota.

How far have the attacks spread?

Another explosion was also reported in Jamundi, a municipality near Cali.

Additional attacks took place in the neighboring department of Cauca, where two car bombs exploded in the towns of El Bordo and Corinto, causing material damage but no casualties. In the town of Caloto, a police officer was killed by a sniper, and another explosion struck the toll booth in Villa Rica, also in Cauca, about 20 kilometers (12.5 miles) from Cali.

The Colombian Army's Third Division, which operates in the region, blamed the attacks on dissident FARC faction led by Nestor Gregorio Vera, alias Ivan Mordisco.

"We express our full support for the police, who were the direct target of these cowardly attacks, and reaffirm our unwavering commitment to the defense and security of our citizens," the military said in a statement.

The attacks came just one day before President Gustavo Petro was scheduled to visit Cali to participate in a public demonstration organized by labor unions in support of his proposed labor reform. The reform faces legislative setbacks and may be pushed through via a national referendum.
