Lebanese media reported that a missile presumably fired by the Hezbollah terrorist militia landed in northern Israel late Sunday night. That report was backed up by resident of the Israeli border town of Metula, who spoke of a high-pitched whistle followed by a loud explosion.
Israeli and Lebanese forces were searching for evidence of the missile strike, but by mid-morning Monday no confirmation had been provided.
Hezbollah's Al-Manar TV later claimed responsibility for the purported missile strike, stating that it had attacked a "settlement" in northern Israel.
The incident came just hours after a Hezbollah stronghold in Beirut was shelled, injuring four of the terror group's members.
It is believed that attack was carried out by Syrian rebel forces angered by Hezbollah's involvement in their nation's ongoing civil war. An estimated 5,000 Hezbollah troops are in Syria fighting on the side of embattled dictator Bashar Assad.
There is also the possibility that Sunday's cross-border missile attack was the start of Hezbollah reprisals for recent Israeli air strikes against the transfer of Syrian weapons to the Lebanese group.
After Israel bombed a facility at Damascus' main airport, destroying a stockpile of weapons earmarked for Hezbollah, Iran reportedly ordered the group to unleash its massive arsenal of missiles against the Jewish state.
Israel this week will conduct a major military drill simulating chemical weapons attacks from Hezbollah on Israeli population centers.
Israeli army officials recently told Israel Today that if another war with Hezbollah breaks out, the IDF will have no choice by to use overwhelming force and quickly conquer Lebanon.
