Explosion at Hezbollah site under investigation

The United Nations Interim Force in Lebanon said it will investigate the cause of an explosion at a Hezbollah arms depot in southern Lebanon.

The explosion occurred overnight Tuesday in an area of southern Lebanon where Hezbollah is prohibited from having weapons under the terms of an agreement that ended the 2006 Second Lebanon War.

UNIFIL controls the area under the terms of U.N. Resolution 1701.

Lebanese security forces were prevented from entering the site of the explosion, the Daily Star reported.
