CAIRO (AP) — Rival Libyan officials on Sunday resumed talks in the Egyptian capital, the latest U.N.-led efforts to agree on constitutional amendments for elections as the North African nation again finds itself at a political impasse.Twelve lawmakers from Libya’s east-based parliament and 11 from the High Council of State, an advisory body from western Libya, were attending the Cairo-hosted talks, said Abdullah Bliheg, the parliament’s spokesman.The U.N. special adviser on Libya, Stephanie Williams, said the talks aim at addressing core challenges — including the political system, eligibility criteria, and a timeline for elections. She advised the attendees that they have until May 28 to come with an agreement.“This session constitutes your last chance to provide a credible response to the expectations of the Libyan people and make concrete progress on these issues,” she said.The first round of the talks
