One Colombian soldier was killed, three injured and one missing after an attack by renegade members of the FARC rebel force acting in defiance of a peace accord, officials said.

"A soldier lost his life and a non-commissioned officer and two soldiers were injured as a result of the explosion," it said.

It said the armed forces were searching for a fifth soldier who went missing after the attack.

"These deeds are attributed to dissidents of the first front of the FARC, who are committing crimes in the region," the statement said.

The leftist FARC are disarming under a peace accord signed last year with the government after more than half a century of civil war.

Dissident members opposed to the accord have broken away and clashed with other FARC members as well as with government forces.

The UN-monitored disarmament process is scheduled to be completed by the end of May.
