US President Joe Biden on Friday vowed to keep up efforts to support a just solution to the Israeli-Palestinian conflict even though the goal of a two-state solution appeared far off. Speaking alongside Palestinian President Mahmoud Abbas in Bethlehem, Biden said the United States would not give up on the goal of a just settlement to the decades-long conflict between Israel and the Palestinians. "Even if the ground is not right at this moment to restart negotiations, the United States and my administration will not give up on trying to bring the Palestinians, Israelis and both sides closer together," he told a joint press conference with Abbas. "There must be a political horizon that the Palestinian people can actually see or at least feel. We cannot allow the hopelessness to steal away the future," Biden said The comments were likely to disappoint the Palestinians, who are looking to the US to press Israel into restarting peace talks. The last substantive talks collapsed over a decade ago. Meanwhile, Abbas said "the key to peace" in the region "begins with ending the Israeli occupation of our land." He added: "I am willing to extend an open hand to Israeli leaders so that we can bring peace to the region." But as Biden said US commitment to a two-state solution "has not changed", Abbas said there was a narrowing window for a resolution of this nature. "The opportunity for a two-state solution on the 1967 borders may be available today, and it may not remain for a long time," Abbas said after meeting with US President. The Palestinian President also asked for US support to holding accountable the killers of Palestinian-American journalist Shireen Abu Akleh, who was killed during an Israeli raid in the West Bank city of Jenin on May 11. Biden said the US would insist on "full" accountability over the killing of the Palestinian-American Al Jazeera reporter. — Agencies
