The escalation comes despite international law experts warning of serious violations by the US, Israel and Iran as civilian infrastructure is targeted.

First, here's our correspondent Katie Watson in Doha in Qatar on the latest there and across the UAE.

Yes, the Gulf nations have warned Iran against targeting water plants, as you mentioned there.

Is there a sense of growing anger in the region?

And what about the mood where you are, Katie?

How much is normal life being affected?

Have you been able to gauge a sense of how people are feeling?

Katie Watson reporting from Doha.

Well, on Thursday, the US and Israel struck one of Iran's biggest unfinished bridge projects.

Iranian authorities say eight people were killed and nearly 100 injured.

What is likely to raise fresh questions about attacks on infrastructure that blurs the line between military and civilian targets.

BBC Persian have managed to make contact with some people in Iran on what they think about the destruction of the bridge.

I feel hopeless.

We will end up with a ruined country.

I'm more disappointed and saddened that I'm in the middle of a situation where I see Iran being destroyed and I can't do anything.

My country is being destroyed more and more every day.

International humanitarian law says attacks must distinguish between combatants and civilians.

The US and Israel insist they're only targeting sites linked to Iran's military or security apparatus.

But the UN's humanitarian chief, Tom Fletcher, strongly condemned the strategy.

This has been a gradual and then very sudden deterioration in the way that we talk about protection of civilians, the way that we talk about international humanitarian law.
