Libya’s warring sides ended several days of U.N.-brokered talks without reaching a deal to consolidate a provisional cease-fire in and around the capital, the U.N. said. Another round of talks was proposed for later this month “as both sides agreed to the need to continue the negotiations,” according to a statement from the U.N. support mission in Libya released Saturday. The current cease-fire was brokered by Russia and Turkey on Jan. 12.
