JERUSALEM -- Four people were reported killed in an apparent terror attack at a synagogue in the Har Nof neighborhood of Jerusalem Tuesday morning, Israeli media reported.

A Magen David Adom spokesman said that there were at least 13 victims, some of whom are gravely injured.

"We are viewing this as a terrorist attack," police spokesman Micky Rosenfeld said.

Two Palestinians, armed with axes and knives, entered the synagogue and began attacking worshipers. Both attackers were shot and killed, Channel 2 reported.

The ultra-Orthodox Har Nof neighborhood sits at the Western edge of Jerusalem.
