Three Russian satellites that were being sent into orbit to complete a navigation system have gone off course and are believed to have crashed into the Pacific Ocean.
A Russian news agency says they came down near Hawaii.
The satellites were being carried by a rocket which blasted off on Sunday from the Baikonur space centre in Kazakhstan.
Officials said the satellites went off course after separating with a booster rocket from the main launch rocket, the BBC reports.
Russia has already successfully launched a number of the Glonass satellites this year.
The navigation system is meant to be in place next year.
