Belgium will wonder if a missed penalty from Axel Witsel will come back to haunt them as they failed to see off Turkey tonight.
The draw hands the initiative to Turkey, who are one point behind second-placed Belgium in Group A, but who also have a game in hand.
It might have been different had Witsel not blazed over the bar with a 75th-minute spot-kick.
That came after Marwin Ogunjimi had given Belgium an early lead, only to see Burak Yilmaz cancel it out in the 22nd minute.
The result will also leave open the question of Turkey coach Guus Hiddink's future, with the Dutchman having said he wanted six points this week or he may offer his resignation having been strongly linked with Chelsea.
Certainly Hiddink, who demanded improvements in his side to prove he was not failing in his task, will not have been impressed as they trailed after only three minutes.
Nacer Chadli fed Ogunjimi, who fired a left-footed shot past Volkan Demirel.
He had a second chance moments later from close range but this time the goalkeeper clung on.
Chances would come thick and fast at either end, with Colin Kazim-Richards going close with a header moments before blocking a shot from Jan Vertonghen after a corner at the other end.
Yilmaz levelled for Turkey in the 22nd minute, meeting Arda Turan's cross for a close-range finish.
Turkey enjoyed a spell of dominance, but poor shooting meant that Simon Mignolet was not tested.
Servet Cetin had a good chance early in the second half, but headed over from a corner.
With the goalkeepers having easily dealt with all that was sent their way, Belgium were handed the chance to make a breakthrough when Arda Turan brought down Dries Mertens in the 73rd minute.
But Witsel went for power over accuracy with his penalty and watched it sail into the stands.
Moments later, Mertens brought a fine save out of Demirel before Chadli wasted a pair of chances and Turkey held out for a point.
