Secretary of State John Kerry extended his Middle East peace mission on Saturday, shuttling between Jerusalem and Amman for more talks with Palestinians and Israelis on reviving their stalled negotiations. Cancelling a scheduled trip to Abu Dhabi, Kerry flew from Jerusalem to the Jordanian capital Amman for yet another meeting with Palestinian President Mahmoud Abbas. He was then due to meet Israeli officials back in Jerusalem later on Saturday. "Because Secretary Kerry's meetings on the peace process remain ongoing in Jerusalem and Amman, we will no longer be able to make a stop in Abu Dhabi," State Department deputy spokesperson Marie Harf said. An Israeli official involved in the talks said Kerry's visit could yield an announcement that Israeli and Palestinian delegates would meet under U.S. and Jordanian auspices. "There is such a possibility, but it is not certain."
