(CNN) -- A string of explosions in a weapons storage facility rattled the village of Shehabiyeh in southern Lebanon and started a fire, Lebanon's official news agency reported.
The state-run National News Agency said preliminary information indicated that the explosion took place in a three-story building "owned by the citizen W.S." and that the Lebanese Army had cordoned off the area and was investigating.
The Israel Defense Forces posted a short video of a burning building on its YouTube channel, saying it was a Hezbollah weapons storage building in Shehabiyeh. The IDF did not say where it got the video, which was shot from high overhead, with text and other markings around the edges of the video blurred out.
A Hezbollah official, however, said that the fire was caused by the explosion of two generators near an area where fuel was stored. No one was hurt, the official said, and the only damage was in the room that held the generators.
New TV Lebanon, a Shiite-owned station aligned with Parliament speaker Nabih Berri, reported that "dozens of fire trucks and ambulances" responded.
