 North Korea has described the latest UN sanctions imposed on the country as an "act of war". 
 
 A foreign ministry statement said the measures were tantamount to a total economic blockade, the official KCNA news agency reported. 
 
 It added that strengthening North Korea's deterrence was the only way to frustrate the US. 
 
 The UN Security Council imposed the new sanctions on Friday in response to Pyongyang's ballistic missile tests. 
 
 The US-drafted resolution - unanimously backed by all 15 Security Council members - includes measures to slash North Korea's petrol imports by up to 90%. 
 
 North Korea is already subject to a raft of sanctions from the US, the UN and the EU. 
 
 What did the North Korean statement say? 
 
 Characteristically bellicose, it described the latest UN sanctions "as a violent breach of our republic's sovereignty and an act of war that destroys the peace and stability of the Korean peninsula and a wide region. 
 
 "The United States, completely terrified at our accomplishment of the great historic cause of completing the state nuclear force, is getting more and more frenzied in the moves to impose the harshest-ever sanctions and pressure on our country. 
 
 "We will further consolidate our self-defensive nuclear deterrence aimed at fundamentally eradicating the US nuclear threats, blackmail and hostile moves by establishing the practical balance of force with the US."

 What exactly are the new sanctions? 
 
 Media playback is unsupported on your device Media caption The US ambassador to the UN, Nikki Haley, said the new sanctions cut oil and petrol imports 
 
 The US said it was seeking a diplomatic solution to the issue and drafted this new set of sanctions: 
 
 Deliveries of petrol products will be capped at 500,000 barrels a year, and crude oil at four million barrels a year 
 
 All North Korean nationals working abroad will have to return home within 24 months under the proposals, restricting a vital source of foreign currency 
 
 There will also be a ban on exports of North Korean goods, such as machinery and electrical equipment 
 
 The UN sanctions came in response to Pyongyang's 28 November firing of a ballistic missile, which the US said was its highest yet. 
 
 US President Donald Trump has previously threatened to "totally destroy" North Korea if it launches a nuclear attack. North Korean leader Kim Jong-un has described the US president as "mentally deranged". 
 
 What about previous sanctions? 
 
 Last month, the US unveiled fresh sanctions against North Korea which it said were designed to limit the funding for its nuclear and ballistic missile programmes. 
 
 The measures targeted North Korean shipping operations and Chinese companies that trade with Pyongyang. 
 
 The UN also approved new sanctions following North Korea's nuclear test on 3 September. 
 
 These measures restricted oil imports and banned textile exports - an attempt to starve the North of fuel and income for its weapons programmes. 
 
 What effect have previous sanctions had? 
 
 The US has been imposing sanctions on North Korea for more than a decade with little success. 
 
 In fact, North Korea has said fresh sanctions will only make it accelerate its nuclear programme. It has continued to test nuclear and ballistic missiles despite these recent examples of UN pressure:

– North Korea now considers itself at war with all 15 members of the United Nations Security Council, according to a blistering statement issued after the council unanimously approved tough new sanctions. The country's foreign minister described the latest round of sanctions as an "act of war" that was " rigged up by the US and its followers," CNN reports. "Those countries that raised their hands in favor of this 'sanctions resolution' shall be held completely responsible for all the consequences to be caused by the 'resolution' and we will make sure for ever and ever that they pay a heavy price for what they have done," the statement said. UN Resolution 2397, issued in response to Pyongyang's ballistic missile tests, slashes North Korea's fuel imports by around 90% and requires the return home of all North Koreans working overseas within 24 months. North Korea's statement said the sanctions were introduced because the US is frightened of its power. The US is "completely terrified at our accomplishment of the great historic cause of completing the state nuclear force, is getting more and more frenzied in the moves to impose the harshest-ever sanctions and pressure on our country," it said, per the BBC. "We will further consolidate our self-defensive nuclear deterrence aimed at fundamentally eradicating the US nuclear threats, blackmail, and hostile moves by establishing the practical balance of force with the US."
