Israel may need to destroy parts of Lebanon and Gaza if Hezbollah and Hamas rain missiles upon the country in response to an Israeli attack on Iran, former Mossad head Danny Yatom said Monday.

Yatom, in an interview on Israel Radio, warned against presenting an apocalyptic picture of how Iran will respond if Israel takes military action against its nuclear program.

While acknowledging that Iran has a few hundred missiles that can reach Israel, and that the price would be horrible if those missiles were equipped with either nuclear or chemical warheads, Yatom said the central concern are the tens of thousands of rockets in Hezbollah and Hamas storehouses in Lebanon and Gaza.

Those rockets, he said, can "cover all of Israel, and that is the main problem."
