Iraq's top Shia cleric has given his support to the new government battling the Islamic State group as militants unleashed a wave of deadly attacks on the country's majority Shia community, killing at least 43 people.
The blitz by the militants this summer plunged Iraq into its worst crisis since US troops left at the end of 2011. While there was no claim of responsibility for Tuesday's attacks, they seemed likely to have been calculated by the group to sow fear among Iraqis and keep pressure on the new Shia-led government in Baghdad.
Prime minister Haider Abadi, who took office last month, met on Monday with top Shia cleric Grand Ayatollah Ali Sistani in the southern city of Najaf. He said after their talks that Mr Sistani welcomed the recent formation of the government that Mr Abadi now leads.
The spiritual leader wields considerable influence among Iraq's Shia majority, and the meeting carried symbolic significance because Mr Sistani has shunned politicians in recent years to protest at how they run the country.
"We have a long and hard mission ahead of us," Mr Abadi told reporters after emerging from the meeting with the cleric, who is believed to be 86 years old. "One of the missions is related to security. We need arms and we need to reconstruct our security forces."
Mr Sistani lives in the Shia holy city of Najaf, 160 kilometres (100 miles) south of Baghdad, and rarely appears in public.
The day's attacks killed dozens in Baghdad and the Shia holy city of Karbala.
In the capital, the bomber blew himself up among Shia worshippers as they were leaving a mosque in a central commercial area after midday prayers. That blast killed at least 17 people and wounded 28, a police officer said.
In Karbala, four separate car bombs went off simultaneously, killing at least 26 people and wounding 55, another police officer said. The city, about 90 kilometres (55 miles) south of Baghdad, is home to the tombs of two revered Shia imams and the site of year-round pilgrimages. The explosives-laden cars were parked in commercial areas and car parks near government offices, the officer added.
Medical officials confirmed the casualty figures.
The attacks in Baghdad and Karbala, the latest in relentless assaults that have challenged the Shia-led government, came a day after a suicide bombing targeted another Shia mosque in the Iraqi capital, killing 28 people.
The latest attacks bore the hallmarks of IS, which has recently claimed several other large bombings in Baghdad and elsewhere, particularly in Shia areas.
The militants have captured large chunks of western and northern Iraq, carving out a proto-state on both sides of the Syria-Iraq border and imposing its own harsh interpretation of Islamic law. Since August, US warplanes have been carrying out air strikes against the group as Iraqi and Kurdish security forces work to retake territory it has seized.
