Hezbollah's deputy chief says Saudi Arabia is committing "genocide" in Yemen and will pay a heavy price for its airstrikes campaign on the Arabian Peninsula country.

Sheikh Naim Kassem says the kingdom made a "strategic mistake" by interfering in Yemen's affairs.

More than two weeks of Saudi-led airstrikes targeting Yemen's Shiite rebels known as Houthis have failed to stop the rebel power grab.

Kassem, who spoke to The Associated Press in an interview Monday in the Shiite group's stronghold in southern Beirut, suggested that the situation inside Saudi Arabia could implode as a result of its "aggression" in Yemen.

He also urges the kingdom to "return to its senses" and halt the airstrikes, and accuses it of supporting al-Qaida's affiliate in Yemen.
