Tzipi Livni (L), co-leader of Zionist Union, is hugged at party headquarters in Tel Aviv March 18, 2015. Prime Minister Benjamin Netanyahu claimed victory in Israel's election on Tuesday after exit polls showed he had erased his center-left rivals' lead with a hard rightward shift that saw him disavow a commitment to negotiate a Palestinian state.Difficult coalition talks still lie ahead. Isaac Herzog, Netanyahu's chief opponent and head of the center-left Zionist Union, said "everything is still open" and that he had already spoken to party leaders about forming a government.
