Four shot dead at Colombia airport

Colombian police say four people have been shot dead by a group of unidentified gunmen at the El Dorado international airport in Bogota.

A police spokesman said three security guards and a fourth man were gunned down inside the cargo terminal.

They were shot as they tried to stop two heavily armed men from breaking into the restricted area.

He said the police were investigating the possibility that the shootings were related to a feud between rival Colombian drug-traffickers.
