The United Nations' top envoy to Lebanon Tuesday expressed hope that Lebanese citizens kidnapped in Syria will be released, saying he was concerned about the situation on the border. Derek Plumbly, the U.N. Special Coordinator for Syria, made his remarks to reporters after meeting with Lebanon's Prime Minister Najib Mikati, spokesman Martin Nesirky said at a news conference in New York. "Mr. Plumbly expressed the hope that all those who have been kidnapped in neighboring Syria will be released without any further delay. He added that it is unacceptable that this situation should continue," Nesirky said. "The Special Coordinator and the Prime Minister also discussed the situation on the border and Mr. Plumbly underlined again the U.N.'s concern that cross-border incursions and shelling continue. The discussions also touched on the work of the United Nations in addressing immediate challenges, particularly the situation of Syrians displaced in Lebanon," Nesirky said.
