Russia said on Thursday it had summoned the British ambassador to voice a strong protest against "offensive" British statements, including about alleged Russian threats to use nuclear weapons.
The Russian Foreign Ministry said it issued the rebuke to Ambassador Deborah Bronnert over "the frankly boorish statements of the British leadership regarding Russia, its leader and official representatives of the authorities, as well as the Russian people".
It said Bronnert was handed a memorandum stating that "offensive rhetoric from representatives of the UK authorities is unacceptable. In polite society, it is customary to apologize for such statements."
The ministry said Russia had told her it objected to British statements containing "deliberately false information, in particular about alleged Russian 'threats to use nuclear weapons'".
No immediate comment was available from Britain's Foreign, Commonwealth and Development Office.
