LONDON (Reuters) - Russia must rein in the activities of its military intelligence officers and account for their actions, British Prime Minister Theresa May said on Wednesday.

“We want Russia to act as a responsible member of the international community. That means it must account for the reckless and outrageous actions of the GRU, which is part of the Russian state,” May told parliament.

“They must rein in the activities of the GRU.”
