* Russian President Vladimir Putin's thinly veiled threat to use nuclear weapons was "dangerous and reckless rhetoric", NATO Secretary General Jens Stoltenberg said. * Russian security forces by late Wednesday detained nearly 1,400 people in 38 cities at protests against Putin's order for the mobilisation of hundreds of thousands of Russians to fight in Ukraine, a rights group said.

Russia pushed ahead with its biggest conscription drive since World War Two while Ukraine demanded "just punishment" for a seven-month-old invasion sending shock waves around the world. FIGHTING

* In Moscow's first update on casualty numbers in Ukraine almost six months, Defence Minister Sergei Shoigu said 5,937 Russian soldiers had been killed since the start of the conflict in February. * Russian forces fired nine missiles at the southern city of Zaporizhzhia, hitting a hotel and a power station, said regional governor Oleksandr Starukh. At least one person was killed with others trapped under rubble, he said. Zaporizhzhia is about 50 km (31 miles) from the nuclear power plant of the same name.

* Ukraine's armed forces said Russia had in the last 24 hours launched eight missile and 16 air strikes and fired 115 anti-aircraft missiles at military and civilian targets, mostly in the Zaporizhzhia and Donetsk areas. DIPLOMACY/POLITICS

* Russian security forces by late Wednesday detained nearly 1,400 people in 38 cities at protests against Putin's order for the mobilisation of hundreds of thousands of Russians to fight in Ukraine, a rights group said. * One-way flights out of Russia were selling out fast after the mobilisation order.
