At least 35 people have been killed in a suicide car bomb attack in a busy square in Iraq's capital, Baghdad, security and medical sources say.

Sixty-one other people were injured by the blast in the predominantly Shia Muslim eastern district of Sadr City.

The Sunni jihadist group Islamic State said it had carried out the attack, which "targeted a gathering of Shia".

Another car bomb later exploded in the car park of the nearby Al-Kindi hospital, killing three people.

On Saturday, IS said it was behind two suicide bombings at a market in Baghdad that left 28 people dead. Again, the reported targets were Shia, whom it regards as apostates.

A number of the victims of Monday's attack are believed to have been daily labourers waiting for work at the 55th intersection in Sadr City.

Three policemen stationed at a local checkpoint were also among those killed.

All of the victims of the attack outside the Al-Kindi Teaching Hospital, just to the south of Sadr City, were civilians, security and medical sources said.

The attacks occurred as French President Francois Hollande visited the Iraqi Counter-Terrorism Service's academy near Baghdad.

He told French soldiers based there that fighting IS in Iraq was helping prevent terrorist attacks at home.

Mr Hollande will later travel to the Kurdistan Region to meet troops advising pro-government forces taking part in the offensive to drive IS militants from the northern city of Mosul, their last major urban stronghold in the country.

Elsewhere in Iraq on Monday, IS militants attacked an army barracks near Baiji, about 180km (112 miles) north of Baghdad, killing four soldiers, security sources told the Reuters news agency.

The militants seized weapons at the base and fired mortars at the nearby town of Shirqat, forcing the authorities to impose a curfew and close schools, officials said.

Gunmen are also reported to have summarily killed nine pro-government Sunni tribal fighters at a village near Udhaim, 90km (56 miles) north of Baghdad.
