Seven police officers killed following president's push for peace

They were leaving a social event in the south-western department of Huila when their vehicle hit a road mine, Qazet.az reports.

They were then shot dead in the ambush, a police spokesperson said.

It is the worst attack on security forces since former guerrilla Gustavo Petro was sworn in as Colombia's first left-wing president less than a month ago.

Images obtained by newspaper El Tiempo showed bodies strewn around a police pickup truck.
