The Lebanese army says Israel remotely detonated a spying device planted in south Lebanon, killing one civilian.

A Lebanese security official, however, says the dead man was a member of the militant Hezbollah group. The official says Hussein Ali Haidar was dismantling the device planted on the group's telecommunications network in Adloun village on Friday when it exploded. The official spoke on condition of anonymity in line with military regulations.

The army says Israel detonated the device "from a distance" through aircraft flying overhead.

The Israeli military declined to comment.

Lebanese and U.N. officials have accused Israel in the past of detonating similar surveillance devices planted in south Lebanon, where Hezbollah guerrillas operate. Hezbollah and Israel, bitter enemies, fought a fierce monthlong war in 2006.
