WASHINGTON (AP) _ Faced with growing international pressure, the Pentagon is changing its policy on cluster bombs and plans to reduce the danger of unexploded munitions in the deadly explosives.



The policy shift, which is outlined in a three-page memo signed by Defense Secretary Robert Gates, would require that after 2018, more than 99 percent of the bomblets in a cluster bomb must detonate.



Limiting the amount of live munitions left on the battlefield would lessen the danger to innocent civilians who have been killed or severely injured when they accidentally detonate the bombs.



Also, by next June the Defense Department will begin to reduce its inventory of cluster bombs that do not meet the new safety requirements.



The new Defense Department plan comes more than a month after 111 nations, including many of America's key NATO partners, adopted a treaty outlawing all current designs of cluster munitions. The agreement also required that stockpiles be destroyed within eight years.



Opponents have complained that the Pentagon has moved too slowly to reduce the cluster munitions from its inventory.



Cluster bombs scatter hundreds of smaller explosives over a large area, where those bomblets can sit for years until they are disturbed and explode.
