White House counter-terrorism adviser John Brennan arrived in Israel on Wednesday for talks with several senior officials, according to a statement from the National Security Council spokesman.

The statement noted that Brennan and Israeli security officials discussed “a range of shared security concerns, including the recent wave of terrorist plots against Israeli and other interests.” It also said that Brennan had held a “productive meeting” with Palestinian Authority Prime Minister Salaam Fayyad.

Brennan arrived after first visiting Bulgaria, where a terrorist blew up a bus carrying Israeli tourists a week ago.
