Calm has been restored in Baghdad, hours after security forces opened fire to stopprotesters storming the Green Zone, reportedly injuring dozens.

Tear gas and live bullets were fired to drive back the mainly Shia Muslim crowds, as they protested against corruption and security failures.

Officials imposed a curfew in the Iraqi capital, which has now been lifted.

It was the second time this month that protesters had managed to break into the city's government area.

Shia Muslim cleric Moqtada Sadr condemned the use of force, and voiced support for the demonstrators' "peaceful [and] spontaneous revolt".

Iraqi PM moves to tackle corruption

At least 50 demonstrators are said to have been wounded.

The protesters accuse the government of neglecting much-needed reforms, as it struggles with its campaign against the so-called Islamic State group (IS) and declining oil revenues.

The Sunni jihadist group controls parts of western and northern Iraq and has been behind a wave of recent attacks that have left dozens killed.
