Managers of shopping malls from New Jersey to San Diego are on alert for terrorist threats and say they are coordinating with law enforcement after release of a Somali extremist group video encouraging deadly attacks.

Westfield Corp., manager of 38 flagship malls across the USA and more internationally said it sees no evidence of an imminent threat to its centers but will take every available step to keep our shopping centers safe.

The company said its top security executives are coordinating with local police and government agencies.

The video threat was released by a southern Somalia based group that took responsibility for a 2013 attack at the Westgate mall in Nairobi, Kenya, that left more than 60 dead.
