NYON, Switzerland -- UEFA has decided to keep Ukrainian and Russian clubs from playing each other "until further notice" because of the continuing unrest between the neighbouring countries.

European football's governing body made the ruling "in light of the current political situation" after the Russian and Ukrainian associations "expressed concerns about safety and security."

The UEFA emergency panel ruling means Russian side Zenit Saint Petersburg and Ukrainian club Dnipro cannot be paired against each other in the Champions League third qualifying round draw on July 18.
