Slaven Bilic dedicated West Ham's point at Anfield to those who died in the bomb blasts in Istanbul on Saturday.
The Hammers manager spent two years in charge of Besiktas and said he was devastated by the tragedy that claimed 38 lives and left scores injured. It occurred just outside the stadium two hours after a game against Bursaspor.
Bilic said: 'Me and my staff were there for two years. I feel for them and I pray for them. It is unbelievable what has happened there.
'Whoever was there, I was all around the world working and taking holidays (there) and they are maybe the best people I ever met.
