Investigators in Kazakhstan have found a huge crater and debris from a Russian rocket which crashed in unpopulated countryside on Thursday.
Kazakhstan is urgently reviewing Russia's rocket launches
The Proton-M rocket was carrying a Japanese communications satellite.
Fragments weighing up to 400kg (880 lb) and a crater 45 metres (49 yards) wide were found in a cattle-grazing area near the city of Dzhezkazgan.
Further Proton launches have been suspended. The rocket was carrying highly toxic fuel when it crashed.
The Russian space agency Roskosmos says a rocket booster motor malfunctioned shortly after launch from the Baikonur cosmodrome.
A similar crash happened in late July, involving a Russian Dnepr rocket.
In the latest incident, Roskosmos promised to pay Kazakhstan compensation for the environmental damage. The crash caused a fire in the steppe, but no casualties were reported.
Kazakh Prime Minister Karim Masimov, quoted by Interfax-Kazakhstan news agency, described the crash as "absolutely outrageous".
Since the break-up of the Soviet Union, independent Kazakhstan has been leasing Baikonur to Russia.
It is the world's oldest space centre - the place where the first ever satellite was launched.
