QINGDAO - A fire in a logistics park in East China's Shandong province was put out Saturday morning after burning for around 10 hours, according to local authorities.

No casualties have been reported.

The fire began at about 4:25 pm Friday in a rubber warehouse at Huajun Logistics Park in Jimo District, Qingdao City, according to the district's Communist Party of China committee.

Around one-third of the 15,000-square-meter warehouse was engulfed by the fire.
