Activists and international delegations stand next to cluster bomb units, during a visit to a Lebanese military base at the opening of the Second Meeting of States Parties to the Convention on Cluster Munitions, in the southern town of Nabatiyeh, Lebanon, Monday Sept. 12, 2011.

If confirmed, deployment of the weapon, especially in crowded civilian areas, would usher in new humanitarian concerns in the conflict, Europe’s largest ground war in generations.
