An explosion at the home of a Hezbollah official in a small Lebanese village has killed at least two people.

Officials say the blast happened Monday evening in Tayr Filsi, a village near the coastal city of Tyre.

Authorities are investigating the cause of the explosion and have not said whether the Hezbollah official was among the casualties.

In July, an explosion at a suspected Hezbollah arms depot in southern Lebanon near the Israeli border raised concerns about the group's weapons caches.

The militant Hezbollah movement fought a 34-day war with Israel in 2006 that killed about 1,200 people in Lebanon and 160 in Israel.
