Russian airstrikes target western arms arriving in Ukraine

Russia is stepping up airstrikes on key Ukrainian supply lines delivering billions of pounds worth of western arms to the country, including on railway lines and warehousing, but the Pentagon insisted the flow of arms had not been significantly impeded.

On Tuesday Russian airstrikes hit six train stations in central and western Ukraine as the Kremlin focused its attacks upon Ukrainian infrastructure, including electrical and water supply substations.

A Russian cruise missile also hit a hangar in Odesa housing Turkish Bayraktar TB2 drones as well as missiles and ammunition from the US and Europe, according to the Russian Ministry of Defence.

The Pentagon spokesperson, John Kirby, noted that, in the past, Russian forces have not had a good record of hitting what they were aiming at.

He suggested that the weapons flows were being sustained by having many alternative supply routes which were continually being changed.

As sources indicated that the UK intends to supply Kyiv with cargo drones to carry supplies on the battlefields in the east and south, the flow of western weapons heading for Ukraine was turning into a flood amid US fears of Russian plans to annex the separatist territories of Donetsk and Luhansk in the east, and the Kherson region in the south.

The early focus of weapons supplies to Ukraine was initially small arms and defensive equipment but that has changed in recent weeks, not least after the announcement by US president Joe Biden of a $33bn (£26bn) support package for Ukraine, including $20bn in military aid.

The supply of weapons to Ukraine has been given a boost after the military experienced shortages and stockpiles of ammunition had dwindled.

The US has already rushed about $3.4bn worth of weapons to Ukraine since Russia invaded on 24 February, including anti-aircraft Stinger systems, Javelins, ammunition and body armour.

The weapons systems being shipped to Ukraine by the US include C-4, howitzers, Mi-17 helicopters, armoured Humvees, M113 personnel carriers, Switchblade drones and M18A1 Claymore anti-personnel mines, with defence sources confirming that dozens of artillery pieces had arrived in country.

The EU has earmarked ¤450m (£380m) for arms for Ukraine, including air-defence systems, anti-tank weapons and ammunition.

The UK is supplying Mastiff heavily armoured patrol vehicles, along with the cargo drones announced this week, and has supplied Ukraine with Starstreak anti-aircraft missiles, 800 anti-tank missiles, and precision munitions.

The rapid increase in arms supplies comes as Russian forces have changed tactics since the first phase of the war, before Russian troops withdrew from their failed assault around Kyiv to focus operations on eastern and southern areas of Ukraine.

Russian forces are now relying more heavily on the intensive use of artillery and rockets against largely outgunned Ukrainian defences, not least in the Donbas region.

The Czech Republic has also sent T-72 battle tanks, while Canada announced last month it had delivered heavy artillery, including M777 howitzers.
