AMMAN - US Secretary of State John Kerry will return to the United States on Friday after consulting Israel and the Palestinians on his effort to revive their peace talks, a senior US State Department official said.

"It is appropriate and encouraging that there is such a serious debate about these issues. We understand that there are many strongly held views and appreciate efforts to find a basis to move forward," the official, who spoke on condition of anonymity, said in an apparent reference to internal Palestinian and Israeli discussions on whether to resume peace talks.
