Ukraine is calling for more Australian military aid in the wake of a Russian missile strike that killed 30 people.

President Volodymyr Zelensky urged allies to send his nation supplies so Ukraine can go on the counter-attack, a call answered by the United Kingdom who will send 14 tanks and other weapons.

More than 70 people were rescued from the high-rise residential building in Dnipro hit by the Russian missile on Saturday, including at least 13 children.

Ukraine’s ambassador to Australia Vasyl Myroshnychenko said the relentless Russian attacks mean more weapons will be needed to withstand the challenge.

Australia has already sent 90 Bushmaster vehicles to Ukraine and 70 Australian Defence Force personnel to the UK to help train Ukraine soldiers, with total support exceeding $650 million.

“At the time Australia is having a summer vacation, Ukrainians are getting killed in large numbers,” Mr Myroshnychenko told ABC Radio.

“We have been very thankful to Australia … for the armoured personnel vehicles … however in order for us to advance and to be able to kick Russians out of Ukraine, we need a different armour and tanks provide that additional armour as well as fighting capabilities.”

But Mr Myroshnychenko said any support would be greatly appreciated, with another tranche of Bushmasters also to provide vital assistance.

“Russians are destroying Ukraine civil infrastructure, their recent attacks on Saturday have targeted six different cities where they have further destroyed power generation,” he said.

“Zelensky has addressed the world and urged everybody who’s hesitating on providing weapons to Ukraine.

“To win this war we need to have the right weapons and to be able to drive Russians out of Ukraine.”

Cabinet minister Bill Shorten said the Defence department would continue to do what it could.

“Australia’s been contributing a great deal – outside of NATO countries we’re the largest contributor to support freedom in Ukraine,” he told ABC Radio.

“That’ll be a matter for the Ukrainian government and discussions with the Australian government and our Defence officials to see what we can do.”

Save the Children has called for international human rights laws to be upheld and the UN Security Council to fulfil its mandate.

“The massive number of civilian casualties sends a chilling note on what the new year will look like for civilians in Ukraine,” the organisation’s Ukraine country director Sonia Khush said.
