Archaeologists have discovered a 3,400-year-old fragment of the world's oldest known peace treaty, the Turkish Ministry of Culture and Tourism has announced.

The agreement, known as the Treaty of Kadesh, was signed around 1269 B.C. by Egyptian pharaoh Ramesses II and Hittite king Hattusili III. Other parts of the treaty have already been found, but the new fragment was unearthed during an excavation at Hattusha, in north-central Turkey.
