Ukraine's army launched a devastating attack on a Russian ammunition depot, causing massive damage. The attack was carried out using a combination of weapons including a FP-2 long-range drone.

The target was a warehouse at Donetsk Airport in occupied Ukraine, where up to 1,000 assembled Shahed drones and 1,500 additional warheads were stored. Satellite images have confirmed the depot was hit and destroyed in the attack, according to Ukraine's army. Further strikes hit arms depots in Horlivka and Dovzhansk, as well as a fuel storage in Luhansk.

Meanwhile the Kirovske airfield in Crimea was again targeted and two hangars housing Orion drones were wiped out.

The airfield is a key base supporting Russia's Orion drones and has been targeted on numerous occasions.

Ukraine also deployed its long-range US-made ATACMS missiles to strike a military training ground base deep inside Russia.

The missiles slammed into the Pogonovo army training ground in the Voronezh region, with reports indicating the presence of a large number of Russian troops at the time of the attack.

Ukrainian military analysts are still trying to clarify the number of casualties suffered by the Russians in the deadly attack. The army base is one of Russia's central facilities for preparing soldiers for the war in Ukraine.

The Pentagon has given the go ahed to Ukraine to use its long-range missiles to attack targets deep inside Russia.

The ATACMS have a range of up to 300 kilometres, and can easily reach targets in Russia's Voronezh, Bryansk, Kursk and Belgorod regions.

The US-made missiles with their 200 kilogram warhead carry a much larger punch than Ukraine's long-range drones.

Their use also forces the Russian command to reposition its air-defence systems away from frontlines to protect rear areas.

This in turn eases pressure on Ukrainian fighter jets and allows deeper drone penetration into Russian-controlled territory.
