A building located inside the fairgrounds in Duesseldorf, Germany, is in flames. The building serves as a shelter for Syrian refugees.
More than 70 firefighters are battling the blast. Residents and visitors in Duesseldorf are asked to stay inside.
Residents in the area were asked by the fire department to close windows and doors.
At this time there is no major trade show and the nearby airport is operating normally. All 180 refuges housed in the shelter are safe.
It appears to be another attack by rightwing extremist in Germany.
