Hundreds of people have gathered in central Ankara to remember the victims of twin suicide blasts that struck the Turkish capital one week ago.
The crowd stood in silence at 10.04am, the time the bombs went off on October 10, killing more than 100 people.
Islamic State is the focus of investigations into the twin suicide bombing, the country's prime minister has said.
Turkish security sources have said "all signs" point to the so-called Islamic State being responsible for twin bombings in the Turkish capital Ankara.
Two senior sources told Reuters News their investigations were focused on IS, following similarities between the attack and a suicide bombing in July in the town of Suruc near the Syrian border.
One source, speaking on condition of anonymity, said: "This attack was in the style of Suruc and all the signs are that it was a copy of that attack ... the signs point to ISIL."
A second official said: "All signs indicate that the attack may have been carried out by ISIL. We are completely focused on ISIL."
