Authorities in central Colombia say about 20 people were injured in a car bomb blast on Sunday.
The explosion occurred near a gas station in the town of San Martin in Meta state. Authorities blame leftist rebels with the Revolutionary Armed Forces of Colombia, or FARC, for the attack.
The bombing was the third in the South American nation in three days.
On Saturday, one person was killed when a car packed with explosives went off along a highway about 50 kilometers south of the capital, Bogota.
Friday, a car bomb blast that authorities said was meant for a passing military patrol killed five civilians, including two children, in northeastern Colombia.
