Roscosmos talking about a failure on the Briz-M?
August 7 during the breeding parent block (RB, "the Briz-M" spacecraft and 2) was not detected in the transfer orbit. The signal from the headunit (GB) was adopted with an emergency intermediate orbit. According to preliminary information, the inclusion of cruise propulsion system (PS), RB, "the Briz-M" was the estimated time. Shutdown control occurred in 7 seconds instead of the estimated 18 minutes 5 seconds. GB means accompanied Troops Air and Space Defense and Space Agency. Conducted an analysis of the situation.

shaky translation or not a 7 second burn doesn't sound good...
Forgive me for not being up to speed (no pun intended) on the Briz-M performance design, but does this strand the satellites in an improper orbit or are they coming back down?
Thanks Jonathan!
My translation, 7 Aug during insertion of the payload module (Briz-KM stage andtwo satellites) it was not delivered to the transfer orbit. A signal from the payload module was received from an erroneous intermediate orbit. According to preliminary information, the ignition of the Briz-M mainengine was carried out at the planned time. Shutdown of the engineoccurred after 7s instead of the planned 18m 5s. Analysis of thesituation [is to be carried out?]
