JINAN - A fishing vessel carrying 10 crew members capsized Tuesday morning off east China's Shandong Province, local authorities said.

The maritime rescue center in Weihai City received a report about a Liaoning-registered vessel overturning in waters of the Yellow Sea around 5 a.m., said a spokesman with the Weihai City Committee of the Communist Party of China.

A total of 37 vessels, including salvaging ships and passing fishing boats, were organized to join in the search and rescue.

The conditions of the people on board remain unknown.

The cause of the overturn is being investigated.
