Hizbullah leader Hassan Nasrallah warned on Thursday that his group will indeed avenge the death of Imad Mughniyeh, despite reports on Wednesday that Israel thwarted a major a Hizbullah-backed terror attack in Europe recently. "The reaction to Mughniyeh's assassination, which will aim to teach the murderers a lesson, is a necessary thing," Nasrallah said. "However, regarding the question of when the revenge will come and what it will be," the Hizbullah leader continued, "don't expect us to answer that." Nasrallah promised that even with future attacks against Israel, Hizbullah would always retain the right to avenge the death of Mughniyeh. "There will never be a day when revenge is behind us," Nasrallah said. "It will always be ahead of us." The most recent threat comes just two weeks before the first anniversary of Mughniyeh's death. In February 2008, Hizbullah's terror chief was killed when his car exploded in Damascus. Despite Israeli denials that it was connected to the assassination, Syrian intelligence and Hizbullah maintain that the bombing was a Mossad operation. On Wednesday, Channel 2 reported that Israeli intelligence agencies recently succeeded in thwarting a major Hizbullah terror attack against an Israeli target in Europe. Last week, Defense Minister Ehud Barak ordered Israeli security services to raise their level of alertness out of fear that Hizbullah would increase its efforts to launch an attack against an Israeli or Jewish target abroad ahead of the February 12 anniversary date. Nasrallah, who made his comments via video link from his place of hiding, also used the opportunity to lash out at the new US president. "The conduct of the new administration when it comes to Israel is ... one of absolute support," he said. "I have not sensed until now that there is any difference between the two (US) administrations."
