Late president Turgut Özal's grave is being opened today as part of an investigation into the cause of his death.

A criminal investigation team, a bomb disposal team, police officers and officials from the Council of Forensic Medicine (ATK) are standing ready at the gravesite.

The case was opened after a number of witnesses spoke of unusual circumstances on the day of the death of the president, who was reported to have suffered from a heart attack. The Ankara Chief Public Prosecutor's Office recently issued a warrant to exhume the remains of the president for toxicology testing.
