At least 14 people were killed and six others wounded in a shooting attack at a dance club in the northeastern Brazilian city of Fortaleza on Saturday.

Two of the wounded were in critical condition. Eyewitnesses say the gunmen arrived at the club in three cars and sprayed bullets into the front of the building for almost half an hour before fleeing. Police say the shooting was "well planned". They are investigating whether the killings were part of an ongoing turf war between two drug gangs. Security in the region is being monitored by helicopter.
