Police in England announced Thursday that the dead assailant responsible for the Yom Kippur attack outside the Heaton Park Hebrew Congregation synagogue in north Manchester was a British citizen of Syrian descent. Although formal identification is still pending, officers believe the person responsible for the attack is 35-year-old Jihad Al-Shamie. A suspicious device worn by the attacker was assessed by specialists and found to be unviable. Two men were pronounced dead after the attack. Police said they continue working to identify the dead and to support their families, the injured, and the community.
