At least seven Colombian soldiers were killed and five others wounded in fighting with Farc rebels on Wednesday, the military said today.
The army claimed that the battle started when about 150 guerillas tried to take Milan in the southern state of Caqueta.
It took place in a rural area consider a Farc stronghold.
The fighting was the deadliest this year. The two sides are holding peace talks in Cuba.
The Farc declared a two-month unilateral ceasefire when the Havana talks began, but that lapsed on January 20 after President Juan Manuel Santos refused to honour it.
Fire Minister Brandon Lewis probably had a fair idea what Sir Ken Knight would deliver when he asked him to conduct an "independent" report into fire and rescue services in England.
