Chaotic scenes have emerged from inside the stadium before the Euro 2024 group stage match between Turkey and Georgia.
The fixture is due to get underway at 5pm UK time at Borussia Dortmund's Signal Iduna Park.
It is largely sold out, with ticket websites showing earlier on Tuesday that just over 1,000 tickets were still available to purchase from the stadium's 65,829 capacity.
However, concerning scenes emerged just over an hour from kick-off, with footage showing the stadium roof leaking heavily onto the seats below.

And further video has shown confrontations and fighting between both sets of fans inside the stadium, with police and stewards called in to intervene.
The Sun initially reported that there are fears the game could be postponed, with groundstaff trying to mop up the standing water on the pitch and in seating areas.
Journalist Daniel Storey, who is at the game, wrote on Twitter: "Think that there has to be a greater than zero chance of this game being postponed if the deluge continues.
"Work ongoing to try and sweep pouring water from stadium corners down drains that have been opened for the purpose, but it's Sisyphean sogginess."
However, Storey has since confirmed that the standing water has been cleared - and that the game is set to go ahead at 5pm.
Georgia are therefore set to play in their first-ever European Championship game this evening, having qualified for the tournament for the first time.
Turkey, meanwhile, will hope to put behind them a nightmare Euro 2020 campaign, where they were considered dark horses but ultimately lost all three of their group stage matches.
They are captained by the Inter Milan playmaker Hakan Calhanoglu, while there is Premier League representation in the form of Manchester United goalkeeper Altay Bayindir and Leicester midfielder Yunus Akgun.
Georgia will be spearheaded by Napoli star Khvicha Kvaratskhelia, with Valencia goalkeeper Giorgi Mamardashvili another key player.
They have one player who plays his club football in England - Watford midfielder Giorgi Chakvetadze.
