Hizbollah fired more rockets into Israel on Wednesday than on any previous day of the 22-day-old war, killing an Israeli and wounding 123, after helicopter-borne commandos launched Israel’s deepest raid into Lebanon.

Israeli sources said around 10,000 soldiers were now battling Hizbollah in southern Lebanon. The United Nations force in the area reported heavy exchanges of fire, with bombings in some areas and intensive shelling across the south.
