Israel and Hezbollah are trading strikes again as the death toll from a massive Israeli bombardment has climbed to nearly 560 people.

There was also a new Israeli airstrike on a southern Beirut suburb on Tuesday, the second day of escalated exchanges across the Israeli-Lebanon border.

Thousands of people fled on Monday from southern Lebanon with the two sides on the brink of all-out war.

Displaced families slept in shelters hastily set up in schools in Beirut and the coastal city of Sidon.

With hotels quickly booked to capacity or rooms priced beyond the means of many families, those who did not find shelter slept in their cars, in parks or along the seaside.
