Huge crowds of protesters marched through Iran's capital. Live from the UK, this is the Marketplace

Morning Report from the BBC World Service. I'm Guy Kilty. Good morning. Tens of thousands of protesters

have taken to the streets of Iran, leading the government to shut down the internet in the country.

Rallies began nearly two weeks ago

after shopkeepers demonstrated against a sharp fall in the value of the Iranian currency against

the dollar. Protesters are now calling for the removal of Iran's supreme leader and at least

40 demonstrators and five security personnel have been killed during the unrest so far.

G.R. Gahl from the BBC's Persian service says that the country's weak economy is the key

reason for the protests. The US-lit sanction has crippled the economy. The value of

Iranian currency rules has sharply fallen against US dollar. And this has created an unsustainable situation

for so many people. Many people are struggling to make ends meet. But also many people are

unhappy about social restrictions and deep anger at political unaccountability, corruption on the highest level among the officials and also their

families. I think there are a combination of so many different reasons. People are coming to the

street. It feels many of them have little to lose. G. R. Gall. The Swiss food and drink giant

Nestle has said it's recalling more batches of its infant formula, this time in Africa, Asia and the Americas.

The BBC's Nick Marsh has been looking at this and has more details. Hi, Nick.

We are talking about a range of Nestle products, specifically the SMA, the Nan, the Bieber,

and the Alphamino baby formulas and follow-on formula products.

I'm sure people listening, parents, young or old, they will be very familiar with

these products, big mainstream products sold all around the world.
