Editor's choice - Blackwater bids for a new US contract
The private military contractor Blackwater is bidding for another big US government contract, to help fight a narcotics trade that the government says finances terrorist groups.
Blackwater was hired by the US State Department to protect diplomats in Iraq and was mired in controversy after a September shooting in Baghdad that left 17 Iraqis dead.
