At least one person died and 13 were wounded in an explosion Tuesday in the southern Pakistani city of Karachi, the local Dawn television station reported.

The blast, which could be heard several kilometers away, occurred next to a furniture factory in the district known as Federal B Area.

The TV station reported that the police cordoned off the site and that the injured were transported to several hospitals.

With more than 20 million residents, Karachi is Pakistan's largest city and one of the ones with the greatest amount of violence.

Criminal gangs and guerrillas incited by political parties and ethnic groups operate in Karachi, which is considered to be Pakistan's crime capital. EFE
