Human Rights Watch has called on Russia and Ukraine to stop using cluster bombs, and urged the US not to supply the munitions to Kyiv, amid reports the Biden administration is poised to include the controversial weapons in a new military aid package.

Russian and Ukraine forces have used cluster bombs, which break apart in the air and release large numbers of smaller bomblets across a wide area.

Russia has fired cruise missiles at a western Ukraine city far from the frontline of the war, killing at least five people in a block of flats, in what officials said was the heaviest attack on civilian areas of Lviv since the Kremlin’s forces invaded Ukraine last year.

The night-time attack destroyed the roof and top two floors of a residential building, injuring nine people as emergency crews with search dogs went through the rubble.

On his recent visit to the US, Boris Johnson “reminded” Donald Trump he “actually played an important role” in supporting and arming Ukraine against its Russian invaders, the former British prime minister said, adding that British aid to Kyiv was “enabled” by Trump’s example.

Johnson made the claim about the notoriously pro-Russian former president – and brushed off mention of Trump’s impeachment for blocking military aid to Ukraine – in an interview on One Decision, a podcast hosted by Sir Richard Dearlove, a former chief of the British intelligence service MI6, and the journalist Julia Macfarlane.

Oleksiy Danilov has described recent days of battle as “fruitful” for Ukraine in terms of destroying the resources of the Russian forces. In a post to social media, the secretary of Ukraine’s national security and defence council described Ukraine as acting “calmly” and “wisely’ in its counteroffensive. He posted:

At this stage of active hostilities, Ukraine’s defence forces are fulfilling the number one task – the maximum destruction of manpower, equipment, fuel depots, military vehicles, command posts, artillery and air defence forces of the Russian army.

The last few days have been particularly fruitful. Now the war of destruction is equal to the war of kilometres. More destroyed means more liberated. The more effective the former, the more the latter. We are acting calmly, wisely, step by step.
