At least two people have been killed and others seriously wounded in a knife attack at a church in San Jose, California

“Our hearts go out to the families of the two community members who have succumbed to stabbing wounds in the attack at Grace Baptist Church downtown,” San Jose mayor Sam Liccardo said in a tweet late on Sunday.

San Jose police said on Twitter that officers had responded to a reported stabbing at the church, and confirmed the two deaths and other life-threatening injuries.

The police added there were no services underway at the time of the attack, but that homeless people had been taken to the church to get them out of the cold.
