Even before Tuesday’s exploding pager attack on Hezbollah, war seemed to be looming on the Israel-Lebanon border. Benjamin Netanyahu began the week promising to return 60,000 evacuees to the north of the country.

A Middle East expert warned that Israel's pager attacks that left thousands of people injured could be the first part of a pre-planned invasion of the southern Lebanon.

Iran's U.N. envoy warned the country had the "right to take all necessary measures to respond to this egregious violation."
