Istanbul football derby cancelled following Turkish intelligence warning
A football match between two of Turkey's most popular football teams has been cancelled following an unspecified threat.
The Istanbul governor's office said Sunday's Galatasaray-Fenerbahce derby was canceled following "the assessment of serious intelligence".
It comes the day after a deadly suicide attack in a busy part of Istanbul left five people dead, including the bomber.
Turkish authorities believe a Turkish Islamic State group militant carried out the bombing.
The Istanbul Derby is one of the most highly anticipated football clashes in Turkish football and sees Galatasaray - on the European side of the city - face bitter rivals Fenerbahce - from the Asian side of the Bosphorus.
The match was due to take place at 8pm at the Turk Telekom Arena but will be replayed at a later date.
"Due to security concerns based on information provided by the TFF, Ä°stanbul council and police force, tonight's match has been postponed," Galatasaray football club said on their Twitter page.
They shared a photo showing a banner at the stadium saying "Your humanity is more worthless than the money you threw [sic]".
Unconfirmed media reports said a bomb threat was to blame for the cancellation.
