Munich is under lockdown after a residential building explosion triggered a massive security operation.
Early reports say a dead man was found at the scene; another individual was found with gunshot wounds.
Authorities also discovered a backpack believed to contain bombs.
In response, officials have shut down Oktoberfest to investigate possible connections.
The explosion happened in a district where nearly 70 percent of residents are migrants, adding tension to the unfolding probe.
