"The Turkish Armed Forces cannot accept anything that might harm the unified structure of the state," said the head of the army, General Ilker Basbug, in an online message

There should be no moves towards contacts with the "terrorist organisation", referring to the rebel Kurdistan Workers' Party (PKK) and its followers, he added, vowing once again to fight them to the end.

Basbug also opposed to granting more language rights to the Kurdish community, as offered recently by the ruling Justice and Development Party.

His message was posted to mark the anniversary of Turkey's victory over Greek troops in August 1922.

In an effort to boost its bid to join the European Union, Turkey has in recent years granted the Kurds a series of cultural concessions, including the launch of a public Kurdish-language television.

Prime Minister Recep Tayyip Erdogan's government has said it is working on a fresh reform package aimed at expanding Kurdish freedoms to erode popular support for the rebels.

They include renaming Kurdish villages that have Turkish names, introducing the Kurdish language as a course in Turkish schools and abolishing references to being "Turkish" in definitions of nationality.
