An Afghan-born U.S. citizen already serving life in prison for a bombing in New York City has been sentenced to an additional life term for a shootout with police in Union County as he attempted to avoid arrest.

A judge sentenced Ahmad Khan Rahimi on Friday. Rahimi was convicted in October on multiple counts of attempted murder and assault. The shooting occurred in Linden, two days after a bomb had exploded in Manhattan's Chelsea neighborhood in September 2016. Thirty people suffered injuries in the bombing, including cuts caused by flying metal and glass. A second bomb planted on the street failed to explode.

Authorities say that prior to the Chelsea bombing, Rahimi also placed a bomb along the route of the Semper Five Marine charity run in Seaside Heights. That bomb went off, but no one was hurt. Federal charges in that case are still pending.

Rahimi didn't address the court during Friday's proceeding.
