Polish Prime Minister Mateusz Morawiecki has warned that over 100 Wagner mercenaries are approaching the Suwalki gap near the Polish-Lithuanian border and may attempt to infiltrate Poland by posing as migrants or Belarusian border guards. This movement is part of a broader campaign to destabilize the border, with around 16,000 illegal crossing attempts this year, allegedly orchestrated by Belarusian President Alexander Lukashenko and Russian President Vladimir Putin. The strategic Suwalki corridor, just 60 miles long, connects the Russian exclave of Kaliningrad to Belarus and is the sole overland link between the Baltic states and the rest of the EU. The presence of Wagner troops in Belarus follows a failed military uprising in Russia and subsequent military training exercises planned with Belarus, raising tensions with NATO and the EU.

Roger Federer made history by becoming the first man to win Wimbledon eight times and the oldest to do so in the Open Era, defeating Marin Cilic, who suffered from a foot blister. Federer's victory marked his 19th major title and his first at Wimbledon since 2012. The 2017 Wimbledon tournament also saw a change of guard in the Ladies' competition with Garbine Muguruza's victory over Venus Williams.
