JERUSALEM, Israel -- Israel Defense Forces Intelligence chief Maj.-Gen. Aviv Kochavi said more than 200,000 missiles are aimed at every part of the Jewish state.
Speaking at the opening session of the 2012 Herzliya Conference Thursday, the Israeli intel chief said Syria and Lebanon house the biggest missile caches.
"Every tenth house in Lebanon is now a weapons depot," he said.
Some of those missiles could be armed with nonconventional or nuclear payloads.
Kochavi said Iran has enriched upwards of four tons of low-grade uranium and about 100 kilos (220 pounds) of 20 percent enriched uranium.
"If those are enriched more, to a 90 percent level, that would be enough for four atomic bombs," he said.
Kochavi said Iran's supreme leader, Ayatollah al-Khamenei, decides on the nuclear weapons program's timetable.
"If Khamenei issues a command to achieve a first nuclear explosive device, we estimate it would take another year before that's achieved," he said.
Kochavi said it's the "duty" of the international community to prevent the Iranian nuclear arms program from "coming together."
"That is the obligation of most of the leaders of the free world," he said, "one that they must meet."
Meanwhile, Israelis in the Sha'ar Hanegev Region Council were told to stay near bomb shelters Wednesday, following an eight-rocket salvo fired from the Gaza Strip.
All seven rockets exploded in open fields and there were no injuries or property damage. The Color Red air raid siren sounded in the southern city of Sderot, urging residents to take shelter against the incoming rocket barrage.
