Israel captain Eli Dasa held up the shoe of a young boy he said was kidnapped by Hamas militants in an emotional tribute during a press conference ahead of the match against Switzerland - before fans displayed banners and posters depicting those detained by the terrorist group.
Around 1,200 people were killed during the attacks on October 7, with more than 11,000 Palestinians who have lost their lives since then from Israeli airstrikes in Gaza.
On Wednesday, meanwhile, Israel fans held up signs bearing the faces of those who were kidnapped during last month's attacks by Hamas, as they played Switzerland in a Euro 2024 qualifier in Hungary.
Shon Weissman scored an 88th minute equaliser for Israel who played out a 1-1 draw with Switzerland, in one of two 'home games' that will instead be ahead in Felcsut - a Hungarian village of around 1,900 people.
It came after captain Dasa, addressing a news conference in Felcsut on Tuesday, raised a small athletic shoe to reporters.

The shoe belonged to a boy he said was kidnapped by Hamas militants last month and was an act of solidarity with Israelis held captive in Gaza ahead of the team's game in Hungary.
'It is hard to speak at the moment, but I don´t think that any of you can guess what is the story behind this shoe,' Dasa said.
'This kid is in Gaza Strip at the moment with seven, seven people from his family.
'That´s all what´s left from his house. This left shoe. We wait for him here,' he continued, before standing up and leaving the news conference.
The shoe was taken from Be'eri kibbutz, the small community in Israel from which eight-year-old Nave Shoham was kidnapped along with seven of his relatives - according to the Israeli team's press officer.
Ahead of Wednesday's game, fans draped in Israeli flags gathered outside the heavily guarded stadium in Hungary, singing chants as their team's bus arrived.
Some fans had travelled as far as Israel to watch their side on Wednesday evening.
Israel's side of the stand was full of flags and placards asking for those who were kidnapped by Hamas terrorists last month to be returned.
Balloons were released by fans to honour those that lost their lives or had been kidnapped during the attacks on October 7
