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.

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.

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