UEFA has confirmed a minute's silence will be held at each of this week's European ties as a mark of respect for the victims of the earthquakes in Turkey and Syria.
Over 33,000 people are confirmed to have died after high-magnitude earthquakes struck southern Turkey and northern Syria last Monday, and the United Nations' aid agency on the ground says that toll is likely to double.
Turkey has said over a million people in the country are using temporary shelters after the tremors, while over five million people are estimated to have been made homeless in Syria.
Ahead of this week's knockout-stage matches in the Champions League, Europa League and Europa Conference League, UEFA has confirmed the details of tributes to show support for those affected.
A minute's silence will be observed before every fixture across UEFA's club competitions this week, while a commemorative banner featuring the message, 'We are together with you', will be displayed in Turkish and Arabic.
A statement released by European football's governing body on Monday also confirmed black armbands could be worn at the discretion of teams and referees.
Last week, UEFA confirmed it would donate €150,000 to the Turkish Football Federation and an additional €50,000 to the Bonyan Organization and Tiafi, both assisting in disaster relief.
Trabzonspor are the only Turkish club in action in UEFA's competitions this week, hosting Basel in the first leg of their Europa Conference League knockout round play-off tie.
Istanbul Basaksehir and Sivasspor advanced to the last 16 of that competition as group winners, while Fenerbahce are into the same round in the Europa League.
Hatayspor and Gaziantep, two clubs based in the region effected by the earthquake, have withdrawn from the Turkish Super Lig.
Former Chelsea, Newcastle United and Everton winger Christian Atsu, who plays for Hatayspor, is still missing.
