Ukraine's acting president, Oleksandr Turchynov, called Tuesday for government forces to relaunch an offensive against pro-Russian rebels after a local politician from his own party was found dead with signs of torture.
Kiev's first push failed last week to retake one of the towns in the mainly Russian-speaking east occupied by the separatists, and its military has largely suspended operations since the United States, Russia, Ukraine and European Union signed a deal in Geneva last week intended to calm the crisis.
But the agreement is already in trouble, with Washington and Moscow putting the onus on each other on Tuesday to ensure that it is implemented, including a stipulation that the rebels must disarm and leave the government buildings they have occupied.
