Iranian leaders are working to give a terrorist proxy the ability to launch guided missiles at Israel’s most important secular and religious sites, according to a top Republican.

“What they intend to do is transfer a GPS capability to what right now are dumb rockets and dumb missiles,” House Foreign Affairs Committee Chairman Ed Royce said Wednesday during an event with the Israel Project. “If they succeed in this, they can pick the tallest buildings in Tel Aviv, the main landmarks in Jerusalem, the airport, the ships in the harbor.”
