A group called the 'Imad Mughniyeh Group' on Monday claimed responsibility for the Jordan Valley shooting which left Yechezkel (Hezi) Ramzarkar, 50, of Ma'ale Ephraim and David Rabinowitz, 42, of Rosh Ha'ayin dead on Sunday night. An anonymous caller from the group, named after the slain Hizbullah arch-terrorist, phoned AFP to take responsibility for the attack. Ramzarkar was laid to rest at 4 p.m. on Monday in Yavne, while Rabinowitz's funeral took place at 12 p.m. in Haifa. The victims' patrol car crashed on Route 90 after shots were fired. Police suspect that the gunmen or gunman may have faked a problem with their car and that when the policemen stopped to investigate, they were shot at point-blank range. A Magen David Adom paramedic crew, accompanied by a military doctor, was dispatched to the area and attempted to resuscitate the victims, but both were declared dead at the scene. The IDF sealed off the area as security forces launched widespread searches for the gunmen. Military sources said the attack could have been an attempt by terrorist groups to thwart a prisoner exchange between Israel and Hamas. Security forces were first alerted to the attack at approximately 8:10 p.m. Emergency responders first believed they were on the scene of a serious accident, but soon realized terrorism was involved when gunshot wounds were discovered on the victims' bodies. A police mobile forensics unit was sent to the scene late on Sunday as security forces attempted to determine what had occurred.
