From various Arab media sources: A blast rocked the outskirts of the Baalbek town of al-Nabi Sheet in Lebanon’s Eastern Mountain Range on Tuesday.

Lebanon's state-run National News Agency said the explosion resulted from the detonation of leftover ammunition near the Lebanese-Syrian border.

Al-Jadeed TV said the blast was caused by "the detonation of an old rocket left over from the 1982 (Israeli) invasion" of Lebanon.

LBCI television for its part said the explosion went off at a Hizbullah post.

Al-Arabiya TV had reported that the blast resulted from an "Israeli airstrike on depots belonging to Hizbullah." It later quoted unnamed sources as saying that "the sounds of blasts east of Baalbek resulted from the detonation of old explosives and not an Israeli airstrike."

Sky News Arabia for its part said that the blast was caused by the detonation of "obsolete ammunition."
