Who was behind the deadly church shooting in Jordan?

Three masked gunmen opened fire on Friday during a funeral at a Greek Orthodox church in Hamoud village, Karak governorate, killing eight people and injuring dozens, according to Jordan’s Ministry of Health. Survivors described an explosion at the start of the service, followed by several minutes of gunfire. Authorities have called the rare attack on a Christian place of worship an act of terror, but the attackers have not been identified. King Abdullah II vowed the harshest penalties and ordered a review of security procedures for responding to terrorist attacks.
