The US state of California is reeling from its third mass shooting in eight days after a man shot dead seven former co-workers south of San Francisco.

The attacks took place in the coastal city of Half Moon Bay, with all victims believed to be Chinese-American farm workers.

The 667year old Suspect Zhao Chunli, was arrested after driving to a police station.

It comes as the state mourns the death of 11 at Monterey Park – during Lunar New Year celebrations.

And just over a week ago, six people including a teenage mother and baby were killed at a property in Goshen, central California.

California Governor Gavin Newsom had tweeted that he was at a hospital meeting with victims of the earlier mass shooting when he was pulled away to be briefed about the second attack, describing it as “tragedy upon tragedy”.
