Hostage Situation at Discovery Channel Headquarters (Updated)S

A man armed with guns and (maybe) explosives has reportedly taken hostages in the lobby of the Discovery Channel's headquarters in Silver Spring, Maryland. Several gunshots have been heard, and authorities are trying to evacuate the building.

This supposed photo of "the gunman" is making the rounds, but it's most likely a law enforcement official.

This is all so bizarre:

Update: The hostage-taker has been identified as James Jay Lee, whose grievances with the Discovery Channel go back a few years. In 2008, he led a "lengthy" protest against the network's headquarters and was eventually arrested for disorderly conduct. You can check out his hilarious list of demands and grievances ("The humans? The planet does not need humans") from the 2008 protest here.

Update: NBC News reports that Lee is dead.
