U.S. special envoy for the Middle East peace process George Mitchell held talks Tuesday with Israeli officials in London in a follow-up to Israeli Prime Minister Binyamin Netanyahu's May 18 visit to the White House, the State Department said Wednesday. “Senator Mitchell was in London yesterday. He met with some senior Israeli officials,” department spokesman Ian Kelly said. “This is part of our ongoing consultations with the government of … Israel, and these meetings were agreed to as a follow-up to Prime Minister Netanyahu's visit earlier.” “All I know is that they … discussed a full range of issues,” Kelly told reporters, adding that Mitchell was due back in Washington on Wednesday.
