Nine members of the former Revolutionary Armed Forces of Colombia (FARC) have been killed in a bombing raid in southern Colombia, the government has said.

It comes after former FARC commanders Ivan Marquez and Jesus Santrich in announced in a YouTube video on Thursday that they were going to take up arms again and resume fighting the government, saying the 2016 peace accords have been betrayed.

The announcement was condemned by the government, the United Nations and the FARC political party, whose leadership said the majority of ex-rebels remain committed to peace despite “difficulties and dangers.”
