BRUSSELS — Police say they opened fire on a vehicle after a high-speed chase in the suburb of Molenbeek and the driver told officers there were explosives inside.

Belgian broadcaster RTL quoted a police spokesman as saying shots were fired at the vehicle after it became stuck in traffic and the driver reversed into a police car.

The report said the vehicle is registered in Germany. Police couldn’t immediately be reached for comment.

A police spokesman told RTL: “We got the driver out, and he immediately told us that there were explosives inside.”

Brussels has been on high alert since 32 people were killed in 2016 suicide attacks. Many suspects linked to those attacks and the November 2015 massacre in Paris lived in or transited through Molenbeek.
