The White House says it is in the early stages of talks to fulfill US President Donald Trump's pledge to move the US Embassy in Israel from Tel Aviv to Jerusalem, an action that would likely spark anger in the Arab world.
"We are at the very beginning stages of even discussing this subject," White House spokesman Sean Spicer said, although aides to Trump say no official announcement is imminent.
Washington's embassy is in Tel Aviv, as are most foreign diplomatic posts.
Israel calls Jerusalem its eternal capital, but Palestinians also lay claim to the city as part of an eventual Palestinian state. Both sides cite biblical, historical and political claims.
Trump, who vowed during the 2016 presidential campaign to move the embassy, was due to speak by phone today with Israeli Prime Minister Benjamin Netanyahu, their first call since the businessman-turned-politician took office on Saturday.
