"The fact that the terrorist who carried out the attack came from the political arm of Hamas obliges the entire international community to recognize Hamas as a terrorist organization," President Yitzhak Herzog announced shortly after arriving in London on a visit to the United Kingdom.
In a statement posted on Twitter, the president wrote that he had been updated on the attack this morning (Sunday) in the Old City of Jerusalem.
"I share the grief of the family and friends of the late Elijah David Kay in their heavy mourning and pray for the speedy healing of the wounded," he wrote.
Earlier, before taking off, the president said he "thanked the British government for its decision to recognize Hamas as a terrorist organization for all that it entails. This is an unparalleled important step in the war on terror. In the dialogue they have with them. "
