Several thousand Iraqis demonstrated in Baghdad Saturday over the burning or damaging of the Holy Qur'an during anti-Islam protests in Sweden and Denmark, in a gathering called by ruling Iraqi parties and armed groups, many close to Iran.
Iran's supreme leader said those desecrating the Holy Qur'an should face the "most severe punishment" and that by defending perpetrators Sweden was gearing for "war" against Muslims.
Many Muslim states have protested at insults to the Qur'an this week in protests in Sweden and Denmark, which both allow the holy book's burning under legal protections for freedom of speech.
Protesters gathered in Baghdad amid heavy security measures, with bridges leading to the Green Zone that houses many foreign embassies shut after an attempt by demonstrators to get to the Danish Embassy in the early hours.
That attempt, repelled by Iraqi security forces who fired tear gas according to a government source, came 48 hours after the Swedish Embassy was overrun and set alight in protest at a planned burning of the Qur'an in Stockholm.
Iraq condemned the attack on the Swedish Embassy but also expelled the Swedish ambassador in protest at the planned burning of the Holy Qur'an, the central text of Islam which Muslims believe to be a revelation from God.
On Friday in Denmark, a man set fire to a book purported to be the Holy Qur'an on a square across from the Iraqi Embassy in Copenhagen.
The event was livestreamed on the Facebook platform of a group that calls itself "Danish Patriots". The video shows the book burning in a tin foil tray next to the Iraqi flag on the ground, with two onlookers standing and talking next to it.
Danish Foreign Minister Lars Lokke Rasmussen condemned it as an act of "stupidity" by a few individuals, telling national broadcaster DR: "It is a disgraceful act to insult the religion of others".
"This applies to the burning of Qurans and other religious symbols. It has no other purpose than to provoke and create division," he said. He noted however that burning religious books was not a crime in Denmark.
Iran's foreign ministry said it had summoned the Danish ambassador on Friday to protest.
Tehran urged Denmark and Sweden to take action, saying Muslims around the world expected the desecration to be stopped.
During Thursday's anti-Islam demonstration in Stockholm, protesters kicked and partially destroyed a book they said was the Qur'an but left the area without setting it alight.
The incident prompted Middle Eastern states including Saudi Arabia and Iran, respectively the region's leading Sunni Arab and Shi'ite powers, to summon Swedish diplomats in protest.
Iranian Supreme Leader Ayatollah Ali Khamenei demanded Sweden hand over perpetrators to Islamic nations' judiciaries.
"The Swedish government should know that by supporting the criminal who burnt the Holy Quran it has gone into battle array for war on the Muslim world," he later tweeted.
Iranian Foreign Ministry spokesperson Nasser Kanaani said the Danish government was responsible for preventing insults to Muslim symbols, as well as punishing offenders. Muslims awaited practical action, he added in a statement on state media.
The Danish foreign ministry could not immediately be reached for comment.
Iran, which has delayed the posting of a new ambassador to Sweden, also said it was reciprocally not accepting a new Swedish envoy over the attacks on the Holy Qur'an.
A Swedish government spokesperson said there was a phone conversation on Friday between the Swedish and Iranian foreign ministers, but declined to give details.
The Iraqi presidency meanwhile called in a statement for international organisations and Western governments "to stop incitement and hate practices, whatever their pretexts".
It also warned Iraqis against being drawn into what it described as a "plot of sedition" which it said aimed to show Iraq was unsafe for foreign missions.
Protests in Baghdad have been led by supporters of influential Shi'ite cleric Moqtada Sadr, a powerful figure opposed to the Iran-backed groups in government, and who analysts say is using the protests as a show of force.
The demonstration Saturday evening was the first major action called by Iran-backed parties and armed groups that back the government.
