UN Secretary General Antonio Guteres stated there is no alternative solution to the two-state solution in resolving the conflict between the Palestinians and Israelis.
Guteres' statement came during a joint press conference with Egypt's Foreign Minister Sameh Shoukry in Cairo.
Guteres met with President Abdel-Fattah El-Sisi Wednesday to discuss regional developments and cooperation between Egypt and the United Nations.
On regional issues, the UN chief underlined the importance of carrying on with the Geneva track on ending the Syrian crisis, as well as providing a suitable atmosphere for reaching national reconciliation in Libya.
Shoukry pointed to talks currently hosted by Cairo between rival political factions in Libya, which could form the foundation of a political settlement to end the country's civil war, reviving the 2015 UN brokered Skhirat agreement.
The Egyptian committee mediating between rival political factions in Libya issued a statement Tuesday night saying it had found common ground between the various parties during talks in Cairo.
