Anyone knows what going on here?

I'm on a TK flight from EU to IST at this moment for transit to TK164 and just got notified TK164 is delayed with over 5 hours. looking at FR24 this seems to have been happening the last 3-4 days as well..

Any info what's the problem?
Guess this is a EU261 case?
Anyone know if TK will provide any sleeping facilities? We were supposed to have a 2 hour layover, now it's 7.
