"Mohammed Shahine was eliminated after recently planning terror attacks, directed and funded by Iran, from Lebanese territory against the citizens of the state of Israel," the military said in a statement, adding that he was killed in the Sidon area.

"Shahine was a significant source of knowledge within the terrorist organisation and was responsible throughout the war for various terror attacks, and rocket launchers aimed at Israeli civilians."

The strike on Lebanon comes on the eve of a deadline in a fragile ceasefire between Israel and Hezbollah.

Lebanese President Joseph Aoun urged sponsors of the deal to pressure Israel into withdrawing troops by Tuesday's deadline.
