CAIRO - Egyptian Foreign Minister Nabil el- Arabi on Saturday called for an international conference to reach a comprehensive solution for the Palestinian cause. In talks with visiting US Senator John McCain, Arabi stressed the importance of urgent work towards peace negotiations between the Palestinians and Israel, according to Egypt's foreign ministry statement. Efforts should be exerted to reach an ultimate and fair solution and the involved parties should avoid prolonged negotiations that do not achieve any real political steps, Arabi added. The talks covered the latest developments in the region, McCain 's visit to Libyan rebels-held Benghazi and results of his meeting with the Libyan opposition. McCain on Friday called on the internationally community to deliver more aids to the rebels' "National Transitional Council" ( NTC) after his one-day visit to Benghazi.
