Israel has reportedly erected a defensive barrier and sonar array off the Ras al-Naqoura border area, in south Lebanon, to prevent Hizbullah divers from infiltrating northern Israel.
Media reports said Israel has obtained information that Hizbullah is investing a large sum of money to acquire undersea weapons and delivery systems to carry out attacks against the Jewish state.
A similar barrier has been deployed off the Gaza Strip.
In 2006, Hizbullah rained more than 4,000 rockets on northern Israel. Hizbullah killed 160 Israelis.
