The football community reacted with shock and sympathy after two bomb attacks rocked central Istanbul following a match on Saturday night.
Two blasts outside the Vodafone Arena in the heart of Turkey's biggest city, two hours after a league match between top teams Besiktas and Bursaspor, killed 38 people and injured over 150.
UEFA expressed condolences to the families of the victims affected by the bombings in a series of tweets.
