Israeli security forces went on heightened alert Monday as the 40-day mourning period for assassinated former Hizballah deputy Imad Mughniyeh came to a close.
Hizballah leaders called for a mass rally in Beirut to mark the end of the mourning period, and said they possess undeniable proof that Israel was behind the February 12 Damascus bombing that killed Mughniyeh.
The Lebanese terror group and its Iranian sponsors have vowed to exact revenge for Mughniyeh's death by attacking Israeli and Jewish targets both in Israel and abroad.
Israeli Defense Minister Ehud Barak said Israel is taking the threats very seriously.
Mughniyeh, a co-founder of Hizballah who was behind the deaths of many Israelis, Arabs and Americans, was also on the hit lists of US security agencies.
