Grace Baptist Church stabbing leaves two people dead, and three others in serious condition.

Police have described the scene at the church as "chaotic" and said multiple stabbing victims required aid from officers and firefighters who rushed to assist.

Video captured from the scene by CBS San Francisco shows a large police presence and a number of emergency vehicles outside the house of worship.

No church services were underway at the time of the stabbing.
