Secretary of State John Kerry said “all the core issues are on the table” in peace negotiations between Israel and the Palestinians and that the talks have intensified.

A meeting Oct. 21 in Jerusalem focused on the issue of sharing water resources, an unnamed Palestinian official told the French news agency AFP. Israeli and Palestinian negotiators met three times in four days.

Kerry confirmed that negotiators have met 13 times since the end of July, when U.S.-brokered peace talks between Israel and the Palestinians were restarted after a hiatus of several years.

“The pace has intensified, all the core issues are on the table and they have been meeting with increased intensity,” said Kerry, who went on to meet with Prime Minister Benjamin Netanyahu in Rome on Oct. 23.
