Turkish MPs have elected Abdullah Gul, an ex-Islamist, as president - despite warnings from the military over threats to the country's secular constitution.
The new president's AK Party enjoys a decisive majority in parliament
The former foreign minister, Mr Gul is well known in international circles and his election has been hailed in Washington and in Brussels, where Mr Gul launched membership talks with the EU.
EUROPEAN COMMISSION PRESIDENT JOSE MANUEL BARROSO
"I want to congratulate you wholeheartedly on your election as President of the Republic of Turkey. I am confident that you will fulfil your task with a strong sense of duty and commitment to your country and fellow citizens.
"In my view, this provides an opportunity to give fresh, immediate and positive impetus to the accession process to the European Union through progress in a number of key areas."
HAMAS SPOKESMAN SAMI ABU ZUHRI
"We consider this an important event that reflects the Islamic wave in this region.
"All the efforts of isolating these people from their history, culture and civilisation have failed. And this is an issue that we call upon the international community to take into consideration."
US STATE DEPARTMENT SPOKESMAN TOM CASEY
"We welcome this exercise in Turkish democracy and I think it continues the course of democratic development in that country.
"We worked very closely with president-elect Gul during his tenure as foreign minister, we expect and continue to do so in his new capacity and congratulate him on his election."
EUROPEAN PARLIAMENT PRESIDENT HANS-GERT POETTERING
"[Mr Gul] is a democratically elected president and as such merits our respect.
"It is important, not just that Turkey espouses European values but this becomes reality."
FORMER TURKISH PRIME MINISTER MESUT YILMAZ
"It would be wrong to evaluate Gul on the basis of his past views. He had ties to a political party then, but now he has none
with any party.
"If he keeps his pledges, he could play a major role in bringing about social peace."
