North Korea has warned the UK it will "pay the price" after No10 introduced sanctions against the secretive dictatorship.
The government announced it would be issuing penalties against groups involved in forced labour, torture and murder in North Korean prison camps.
The country's state media reportedly said that "the United Kingdom, a puppet of the US, committed a provocation".
The move against the two organisations - named as the Ministry of State Security Bureau 7 and Ministry of People's Security Correctional Bureau - is part of the first sanctions under Britain's new global human rights regime.
Sanctions on 25 Russians and 20 Saudis were also announced.
"Britain's latest move is a flagrant political plot to jump on the bandwagon of the United States' inimical policy," a North Korean Foreign Ministry spokesperson said in a statement carried on state media KCNA.
"We strongly condemn and reject the UK's daring to impose sanctions on the institutions responsible for our country's security as violent interference in domestic affairs."
The sanctions will take the form of asset freezing.
North Korea and the United States have failed to find a compromise over North Korea's nuclear weapons programme or international sanctions imposed on Pyongyang.
Yesterday, Kim Jong-un's sister has made a rare statement to say North Korea "won't be threatening the United States" as the country refused to take part in another summit.
Kim Yo-jong, the sister of North Korea'a leader, said another summit with the United States would only be useful for Washington at this point.
According to state media she then said her country had no intention of "threatening the US".
Kim said in her personal opinion, there is unlikely to be another summit between leader Kim Jong-un and US President Donald Trump this year but "a surprise thing may still happen," news agency KCNA reported on Friday.
US Secretary of State Mike Pompeo said on Thursday he was "very hopeful" about resuming talks with North Korea about denuclearisation and appeared to leave open the possibility of another summit between the countries' leaders.
