<div style="text-align: justify; "><b style="font-size: 1rem;">Vladimir Putin has said the threat of a nuclear war was rising, but insisted Russia had not "gone mad" and would not use its nuclear weapons first.</b><br></div><div style="text-align: justify; "><br></div><div style="text-align: justify;">The Russian president insisted that his country would only use weapons of mass destruction in response to an attack.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Speaking at Russia's annual human rights council meeting, he also said the war in Ukraine could be a "lengthy process".</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Western officials believe Putin initially planned for a rapid victory.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Russia's capacity to use nuclear weapons has come under increased scrutiny since it invaded Ukraine in February.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">"Such a threat is growing, it would be wrong to hide it," Putin warned while talking about the prospect of nuclear war via video link from Moscow.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">But he asserted that Russia would "under no circumstances" use the weapons first, and would not threaten anyone with its nuclear arsenal.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">"We have not gone mad, we are aware of what nuclear weapons are," he said, adding: "We aren't about to run around the world brandishing this weapon like a razor."</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Putin also boasted that Russia had the most modern and advanced nuclear weapons in the world, and contrasted its nuclear strategy to the US - who he said had gone further than Russia by locating its nuclear weapons on other territories.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">"We do not have nuclear weapons, including tactical ones, on the territory of other countries, but the Americans do - in Turkey, and in a number of other European countries," he said.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Putin has previously insisted that Russia's nuclear doctrine only allowed for the defensive use of nuclear arms.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Appearing to recognise that his plan to claim victory within days of invading Ukraine had failed, Putin admitted the war could be a "lengthy process".</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">However, he said the results had already been "significant" - for example, the new territories Russia has illegally claimed after sham-referendums in four regions of Ukraine.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">He boasted that the annexations had made the Sea of Azov - which is bordered by south-east Ukraine and south-west Russia - an "internal sea" of Russia, adding that this was an aspiration of Russian Tsar Peter the Great. President Putin has compared himself to the 17th and 18th Century ruler before.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">But - despite claiming the regions of Kherson, Zaporizhzhia, Luhansk and Donetsk as Russia's new territory - Moscow does not fully control any of those areas.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Last month, Russian forces were forced to retreat from Kherson city, the only regional capital they had seized since the February invasion.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The setbacks on the frontline have led to Russia targeting Ukraine's power grid by launching massive air strikes across the country,</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The airstrikes have caused widespread damage to Ukraine's energy infrastructure, leaving millions without heating and electricity for hours, or even days, as temperatures dropped below zero.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">The Mayor of Kyiv, Vitali Klitschko, warned that Ukraine's capital - which has been badly affected by power cuts - could face "apocalypse".</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">"Kyiv might lose power, water, and heat supply. The apocalypse might happen, like in Hollywood films, when it's not possible to live in homes considering the low temperature," Mr Klitschko told Reuters in an interview.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Though heated shelters have been set up in the city, Mr Klitschko admitted there were not enough for all residents, and people should be ready to evacuate if the situation worsens.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Back in Russia, any potential criticism of Putin's invasion was stymied before the human rights council.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">In the run-up to Wednesday's meeting, 10 members of the council who had expressed doubts about the war were removed. Pro-war replacements were brought in instead.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Subjects to be discussed during the meeting were also heavily vetted beforehand, according to the independent Russian news outlet Verstka.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">In recent weeks, Russia's nuclear doctrine has come under close scrutiny on when nuclear arms could be used, in particular a "tactical" weapon that might be unleashed on the battlefield in Ukraine.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">A tactical nuclear weapon is for use in combat, as opposed to the larger "strategic" weapons which are designed to cause massive destruction.
