Strike on Lviv that used nuclear-capable ballistic missile a ‘dangerous, inexplicable escalation’. What we know on day 1,420

The US and Britain have condemned Russia for dropping a nuclear-capable Oreshnik ballistic missile on Ukraine. At an emergency meeting of the UN security council, Tammy Bruce, US deputy ambassador, called the Lviv strike a “dangerous and inexplicable escalation”. Britain’s acting UN ambassador, James Kariuki, called the attack “reckless”, adding that “it threatens regional and international security and carries significant risk of escalation and miscalculation”.

Russia claimed the Oreshnik targeted an aviation repair factory. Ukraine has not confirmed what was hit but said the missile struck during a wider attack using drones and other rockets. The rarely used, multiple warhead Oreshnik missile is thought to be in limited supply – Ukraine’s military and special forces claim to have destroyed at least one of them on the ground in Russia. Observers have rated the two Oreshnik strikes so far on Ukraine as largely political and symbolic, with dummy warheads probably used, and any damage caused by their sonic boom and physical impact rather than live explosives. Analysts have questioned whether the Oreshnik is accurate enough to deliver non-nuclear bombs, which have to be more closely targeted than nuclear warheads to be effective.

Russian forces launched attacks on Kyiv and Kharkiv early on Tuesday, killing at least four people in Kharkiv, according to its mayor, Igor Terekhov, and injuring another six. In the southern city of Odesa, residential buildings, a hospital and a kindergarten were damaged, with at least five people wounded in two waves of attacks, said Sergiy Lysak, the regional governor.

Kyiv on Monday buried medic Sergiy Smolyak, 56, who was killed in a drone attack as he rushed to rescue residents from a housing block that Russia struck minutes earlier in a massive attack on the Ukrainian capital on Friday. “He was very kind, always calm and even-tempered. He saved so many people,” said Ryta Dorosh, a nurse who worked with Smolyak before the war.

Russia has bombed two more civilian ships transporting food products in the Black Sea, according to Ukraine. “An enemy drone struck a Panamanian-flagged tanker that was waiting to enter port to load vegetable oil. Unfortunately, one crew member was wounded,” said Ukrainian regional development minister Oleksiy Kuleba. “There was also an attack on a ship flying the flag of San Marino, which was leaving the port with a cargo of corn ... This is further proof that Russia is deliberately attacking civilian ships, international trade and maritime safety,” he added. Odesa regional governor Oleg Kiper said the attacks happened around the Chornomorsk port on the southern Ukrainian coast.

UK government starts contest to have deep-strike prototypes delivered within 12 months; heat-starved Kyiv under Russian attack again. What we know on day 1,419

Britain is to develop a new deep-strike ballistic missile for Ukraine, the government has announced. Under the project, named Nightfall, the British government said on Sunday that it had launched a competition to rapidly develop ground-launched ballistic missiles that could carry a 200kg (440lb) warhead to a range of more than 500km (310 miles).

“Nightfall missiles will be capable of being launched from a range of vehicles,” said the UK defence ministry (MoD), “firing multiple missiles in quick succession and withdrawing within minutes – allowing Ukrainian forces to hit key military targets before Russian forces can respond.”

Three industry teams would each get £9m to design, develop and deliver their first three Nightfall missiles within 12 months for test firings, said the MoD. Ukraine’s current ballistic missiles include Atacms, for which it relies on the US, and the self-developed Sapsan.

Russia was again attacking Kyiv early on Monday, the Ukrainian military said, sparking a fire in at least one district. Ukrainian air defences were at work against incoming targets, said Timur Tkachenko, head of Kyiv’s military administration.

The renewed attack came as more than 1,000 apartment buildings in the Ukrainian capital remained without heating because of a Russian bombardment on Friday. Volodymyr Zelenskyy, Ukraine’s president, said that despite repairs the situation was “still extremely difficult”, particularly in border regions.

At the Vatican, Pope Leo offered prayers for the people of Ukraine, saying the “particularly serious” strikes on energy infrastructure were “hitting the civilian population hard, just as the cold weather is getting worse … I pray for those who are suffering and renew my appeal for an end to violence and for efforts to achieve peace to be intensified.”

Ukraine’s forces hit three drilling platforms operated by Russian oil company Lukoil in the waters of the Caspian Sea, the Ukrainian military general staff announced on Sunday. The strikes on Russian energy sites aim to deprive Moscow of oil export revenue used to fund the war. Moscow meanwhile said a Ukrainian drone strike killed one person and wounded three others in the Russian city of Voronezh.
