CIA Chief John Brennan has made an unannounced visit to Israel.
According to an anonymous Israeli Defense Official, Brennan met with Israel's Defense Minister.
This trip comes amid concerns about weapons transfers from Syria to Lebanese terror group Hezbollah.
Israel has carried out air-strikes aimed at halting arms shipments to the group.
This week, Prime Minister Benjamin Netanyahu also traveled to Russia to persuade Moscow not to sell an air defense system to Syria.
