Israel Home Invasion by a Terrorist, thwarted
What the terrorist did not know is that Yael is an athlete trained in Krav Maga, Israeli military hand-to-hand combat. She used her skills to drive him back and into the bathroom, and locked him in. At the same time, she pushed her young children to safety.
Once the terrorist was locked away, she called for help. IDF forces arrived only to see the terrorist escaping through a bathroom window. They gave chase and attempted to arrest him, but were forced to open fire when he refused to drop his weapons. The terrorist was killed. [Emphasis added]
I'd never heard of Krav Maga. Take a look at the video starting at about 1:20; it seems to be a type of martial arts that incorporates dealing with knives, hand-guns and machine guns.
