Turkish President Tayyip Erdogan will travel to Greece on Dec. 7-8, Greek sources said on Friday, in the first visit by a Turkish president in decades that have seen ties at times severely strained over issues from Aegean Sea rights to ethnically-split Cyprus, Reuters reported.

Erdogan is expected to meet his Greek counterpart and Prime Minister Alexis Tsipras and discuss bilateral relations, security issues and the refugee crisis, following a 2016 EU-Ankara deal aimed at reducing migrant flows to Europe.

He is also expected to visit Thrace in northern Greece, where there is a Muslim minority.

Erdogan last visited fellow NAT member Greece in 2010 in his capacity as prime minister. His visit next week will be the first by a Turkish president to Greece in 65 years.

Greece and Turkey, NATO allies, came to the brink of war in 1996 over the ownership of uninhabited Aegean islets.
