European football's governing body Uefa announced a "moment of silence" before Tuesday's Euro 2024 qualifiers, in memory of the two Swedish fans shot dead in Brussels.
Two fans were killed and one other injured by a suspected Islamist before Sweden's match against Belgium at the King Baudouin Stadium on Monday.
The Group F encounter was halted at halftime with the score at 1-1, following consultations between the two teams and local police authorities.
The travelling Swedish supporters were held in the ground for security reasons, before being escorted away under police protection at around 2 am local time.
On Tuesday, the suspected attacker, a radicalised 45-year-old Tunisian national living illegally in Belgium, was killed in a police operation.
The Swedish FA's head of security Martin Fredman said on Tuesday that the Red Cross would be present in Arlanda and Bromma airports in Stockholm to offer support to returning fans.
Fifa has put the Swedish flag at its Zurich HQ at half-mast and President Gianni Infantino wrote on Instagram that he was "shocked" and "saddened" by the shootings.
