Palestinian leader Mahmud Abbas met Colombian President Juan Manuel Santos in the occupied West Bank on Tuesday, a day after Israel's closest South American ally signed a free trade deal with the Jewish state. Colombia was one of a minority of states to abstain in a vote on upgrading the Palestinians' status at the United Nations in November which passed with overwhelming international support. Abbas and Santos discussed "the peace process... and the establishment of an independent Palestinian state based on 1967 borders," the Wafa news agency quoted Abbas as saying. They also talked about "strengthening bilateral relations," he added. Santos then returned to Jerusalem where he went straight into talks with Israeli Prime Minister Benjamin Netanyahu on what was the third day of his visit.
