Israel and Lebanon exchanged heavy fire into Sunday, with Israeli warplanes carrying out the most intense bombardment in almost a year of war across Lebanon's south, while Hezbollah claimed rocket attacks on military targets in Israel's north.

Hezbollah has launched over 100 rockets across a wider and deeper area of northern Israel, with some landing near the city of Haifa, as the sides appeared to be spiraling toward all-out war following months of escalating tensions.
