U.S. President George W. Bush begins his tour of Europe in Prague before the G8 summit in Germany. During his visit, he intends to address the deployment of interceptor rockets, the establishment of radar bases in Poland and the Czech Republic, and the related tension that has arisen between the United States and Russia.
- The Prime Minister of the Czech Republic, Jan Fischer, says that President Barack Obama told him that the United States is abandoning plans for a missile shield based in Poland and the Czech Republic.
- US President George W. Bush claims that the United States and Russia had almost reached agreement on Russia joining the World Trade Organisation. Bush met with Vladimir Putin prior to the G8 meeting in Strelna.
- Poland's Minister of Defence Mariusz Blaszczak says he recently talked with U.S. officials in Washington D.C. about permanently stationing thousands of U.S. troops in Poland as a deterrent against Russia.
- A court in Radom, Poland, hands a six-month suspended prison term and a 10,000 zloty fine to a Russian pilot who caused a security scare during Pope Francis's 2016 visit for World Youth Day. The Russian had flown from the Czech Republic to compete in an international aerobatics competition and unknowingly violated a no-fly zone imposed for the papal visit. After failing to contact the aircraft, local authorities scrambled two F-16 fighter jets to intercept it.
- The United States and Russia begin fighting over the extradition of Yevgeniy Nikulin, who was detained in October 2016 in the Czech Republic, after the U.S. Justice Department issued an international arrest warrant for him. However, soon after the U.S. issued its arrest warrant, Russian authorities also sought his extradition. The Russian charge accuses Nikulin of stealing from an online money transfer company back in 2009.
