Authorities in Ecuador have extended the state of emergency in Guayaquil and the surrounding cantons of Duran and Samborondo until at least October 12.
The state of emergency gives security forces more flexibility to fight organized crime.
It was initially declared in response to an August 14 car bomb attack in Guayaquil that killed five people.
Under the state of emergency, the authorities can partially suspend certain rights and freedoms.
Authorities may also set up security checkpoints and restrict movement, especially after dark.
Law enforcement authorities may increase patrols and/or conduct warrantless searches of vehicles, persons or premises.
Authorities can impose a curfew if they deem the situation to be justified.
Localized business and traffic disruptions are expected for the duration of the state of emergency.
Further security incidents, including other car bombs, cannot be ruled out in the coming days and weeks, especially as authorities are likely to launch operations to track down and arrest suspected criminals.
The August 14 car bomb attack was the latest in a series of attacks that have occurred in Guayaquil in recent months.
On May 29, a car exploded outside a police station in the city. A similar incident occurred on April 25 in front of a prison in Guayaquil.
