Ukraine's Ministry of Defence has issued a graphic telling people how to launch a Molotov cocktail at a tank.

It came as brave Ukrainians were seen hurling DIY petrol bombs at a Russian tank from the window of a passing car.

Remarkable footage shows people in the car shouting abuse at Putin's forces, before a woman throws the home-made weapon directly at the armoured vehicle.

The Ministry of Defence and the Ukrainian army's General Staff posted detailed instruction on how to make Molotov cocktails and where to aim when faced with a Russian tank or truck. 

Civilians have been encouraged in recent days to make their own petrol bombs, with President Zelensky's embattled government even giving out a DIY flyer with instructions. 

A post from the verified Twitter page of the Ministry of Defence of Ukraine last week said: 'In Obolon... We ask citizens to inform about the movement of equipment! 

'Make Molotov cocktails, neutralise the occupier! Peaceful residents - be careful! Do not leave the house!'

More footage over the weekend showed hundreds of civilians of all ages making the weapons as part of efforts to arm themselves against Russian attackers.
