The mayor of Haifa in northern Israel says he is grateful for threats made by Hezbollah leader Hassan Nasrallah to attack the city's ammonia facility.

In 2006 Israel fought a war with the militant group in Lebanon, but when Nasrallah said Tuesday that "several of our rockets combined with the ammonia storage facility in Haifa will create the effect of a nuclear weapon," the local mayor seized the opportunity to highlight his city's environmental problems.

Yona Yahav says "we are happy for help" in putting the environmental issue on the agenda, "even if it arrives from a frightened man hiding in his bunker."

He says Haifa faces environmental threats from the ammonia facility and an oil refinery.

Israel's environment ministry says it plans to move the facility to southern Israel.
