BEIJING (Reuters) – More than 10,000 trucks mainly carrying coal are stuck in a 120-kilometer traffic jam in the northeastern Chinese region of Inner Mongolia, in the latest dramatic snarl-up on the country's roads.

State television said the highway heading towards Beijing and the neighboring province of Hebei was now more like a car park.

The jam started forming on Tuesday after traffic restrictions began being enforced in Hebei, it added. Most of the vehicles were coal trucks, the report said, which were also blocking feeder roads leading onto the highway.
