Things are heating up over there. Hezbollah, the militant group, captured two Israeli soldiers during clashes along the Lebanese border. The response, in action, was swift: An Israeli effort to find the captives featured an assault by warplanes, tanks and gunboats. The response, in words, was succinct:

Israeli Prime Minister Ehud Olmert called the guerrilla attack "an act of war" and warned that Hezbollah would pay a "heavy price" for its actions.

UPDATE: The Israeli Defence Force is calling up reservists.

UPDATE 2: Reports say seven Israeli soldiers have been killed.
