Turkey's Children's Day is the world's only holiday dedicated to children, Prime Minister Ahmet Davutoğlu said Saturday.

Addressing a special session of the parliament on National Sovereignty and Children's Day, Davutoğlu said: "23 April is the only children's holiday in the world."

Every year, Turkey marks April 23 as the day in 1920 the first parliament of the republic was held. The country's founder Mustafa Kemal Atatürk said the day should be focused on children as the representatives of Turkey's future.

Celebrating the 96th anniversary of the first Grand National Assembly, Davutoğlu said: "Let's stand shoulder to shoulder for this country's future."

He added: "We have a common historical story that binds us. We should never forget this historical story that enables [us] looking together at the future which binds us."

The leader of the main opposition party Kemal Kılıçdaroğlu said the day was the "only and the first holiday that was dedicated to world's children." Kemal Kılıçdaroğlu, who heads the Republican People's Party (CHP), said Turkey's parliament was among the oldest in the world.

Nationalist Movement Party leader Devlet Bahçeli said: "The first parliament was the sign of hope and a declaration of the existence of the Turkish people."

Çağlar Demirel, deputy chairman of the Peoples' Democratic Party (HDP), also spoke during the special parliamentary session.
