CBNNews.com - JERUSALEM, Israel - Following the assassination of terrorist mastermind Imad Mugniyeh Tuesday night, the Shin Bet (Israel's General Security Agency) instructed Israeli embassies, Jewish Agency branches and El Al airlines to heighten their alert level.
Israeli intelligence agencies will focus on gathering information for possible revenge attacks on consulates, embassies and other Jewish entities abroad.
"After events like this, we need to sharpen our senses in preparation for a retaliatory attack," one security official said.
Threats have run the gamut from the Lebanese-based Hezbollah terror group, which Mugniyeh co-founded, to Iranian officials, to Gaza-based Hamas terrorists and other Islamic groups.
"This despicable crime will increase the Zionists' disasters and strengthen the courage of those who will hit the Zionist regime," said Ahmad Moussavi, Tehran's ambassador to Damascus on IRNA, the Iranian state news agency.
"His pure blood, just like the blood of the other fighters, will claim a heavy price from the enemy," Moussavi threatened. "The death of [Hezbollah's] Imad Mugniyeh will lead to an earthquake in the Zionist regime," he said.
"This action is a clear result and example of organized state terrorism by the Zionist regime," said Iranian Foreign Ministry spokesman Mohammad Ali Hosseini.
Israelis traveling abroad, including post-army backpackers in South America, India and Africa, and businesspeople abroad should also be on heightened alert against attacks or abduction.
Israel raised the level of alert along the northern border with Lebanon as well.
In a videotaped eulogy broadcast on a giant screen at Mughniyeh's funeral Thursday, Hezbollah's spiritual leader Hassan Nasrallah declared war on the Jewish state.
"You have killed Hajj Imad outside the natural battlefield," Nasrallah said. "You have crossed the borders. With this murder, its timing, location and method -- Zionists, if you want this kind of open war, let the whole world listen: Let this war be open," he said.
