A British minister has refused to declare the school massacre in Iran, which killed 165 people, many of them children, a war crime, labelling it the "realities of war".

On 28 February, the day the US and Israel launched their attack on Iran, a double-tap strike targeted the Shajareh Tayyebeh School, a girls' primary school in the city of Minab.

US investigators probing the attack said last week they believe the US military was likely responsible for the attack.

And newly released footage this week suggests a US Tomahawk missile hit the school.

In an interview with Sky News on Tuesday morning, Courts Minister Sarah Sackman was asked for her "reflections on the evidence that has come to light".
