Cairo/Amman - Egypt blamed Palestinian militant groups Wednesday for this week's rocket attacks on Israel and Jordan, though the Hamas movement rejected the allegations. A security official in Cairo, requesting anonymity, said Palestinian militants were behind Monday's attack, which killed one Jordanian and injured five others in the Red Sea port town of Aqaba. The rocket which fell in the neighbouring Israeli coastal city of Eilat did not cause any injuries. The official did not specify where the attack was launched, though Amman has claimed that the rockets came from Egyptian territory. The Hamas movement in the Gaza Strip issued a statement rejecting a Palestinian link to the rocket fire and even questioned whether the incident took place. The Islamist group said Israel was at fault. Meanwhile, an official newspaper in Jordan reported the government had 'proof' the Grad-type rocket that hit Aqaba, a resort area, was launched from the Sinai Peninsula. 'The authorities have identified the location from which the rockets were launched and have strong clues about who was behind the attack,' an unidentified official was quoted as saying in the Jordan Times. Egyptian officials have categorically denied that the rockets were fired from Sinai. South Sinai's governor said the area was too mountainous to launch the rockets. 'Jordan will not hesitate to take any necessary action against anyone or any party tempted to harm the kingdom's security and stability and to pursue the perpetrators of this criminal attack,' a cabinet statement from Amman said. Jordan and Egypt are the only Arab countries to have full peace deals with the Jewish State.
