Iraqi joint forces began recently a number of battles to liberate the last areas controlled by ISIS extremist group in the Iraqi city of Mousl, as they managed to liberate Saa Church. Meanwhile, leader of Federal Police revealed that stormed the old city of Mousl’s right bank from the southern area.

Iraqi forces said Tuesday they were fighting fierce battles with the Daesh terror group and rescuing escaping civilians as they pursued their offensive against Mosul’s extremist-held Old City. Staff Lieutenant General Abdulghani Al Assadi, a senior commander in the Counter-Terrorism Service (CTS), said the battle was proceeding as expected but that progress was slow.

 “We have many obstacles — the nature of the land, the nature of the construction, the roads and the civilian population — all of which make us slow down our work.”  He said civilians were escaping from the Old City, with up to 400 approaching the positions of Iraqi forces on Monday.

Federal police forces said they were moving forward on the southern front of the battle with support from heavy weapons fire and on the northern front had surrounded a hospital. Iraqi forces launched the operation on Sunday to retake the Old City, the last part of Iraq’s second city still held by Daesh after a months-long offensive.

Commanders say the extremists are putting up fierce resistance and there are fears for more than 100,000 civilians believed to be trapped in the maze of narrow streets, and the UN has said Daesh could be holding them as human shields.

The UN children’s agency, UNICEF, said Tuesday that tens of thousands of children were among the civilians trapped in the Old City, and that those who managed to flee were traumatised. “50,000 children are trapped in the Old City of west Mosul in absolutely horrifying conditions,” said Peter Hawkins, UNICEF representative in Iraq.

“Many children fleeing the violence are severely distressed and need psychological care,” he added, calling on all parties involved in the conflict to provide safe passage for civilians. Iraqi forces have been inching forward in the face of heavy sniper and mortar fire and booby-traps laid by the extremists.

On Monday, three French journalists were wounded and Kurdish reporter Bakhtiyar Addad killed in a mine explosion while accompanying Iraqi forces in Mosul. French public broadcaster France Televisions said Tuesday that one of the wounded journalists, Stephan Villeneuve, had died of his injuries.

The push into Mosul’s historic heart on the west bank of the Tigris River marks the culmination of a campaign launched in October by Iraqi forces to retake Daesh’s last major urban stronghold in the country.

The US-led coalition battling Daesh in Iraq and neighbouring Syria has backed the offensive, including with months of air strikes. The loss of Mosul would mark the effective end of the Iraqi portion of the cross-border “caliphate” that Daesh declared in summer 2014 after seizing swathes of Iraq and Syria.

Earlier this week, Iraqi forces dropped nearly 500,000 leaflets over the city, urging civilians to stay indoors and escape if they can. They have also stationed Humvees facing the Old City mounted with loudspeakers telling IS fighters: “You have only this choice: surrender or die”.

Surrounded by Iraqi forces on three sides and blocked on the other by the Tigris that runs through Mosul, the fighters are cornered. Commanders have said the battle could last weeks. Iraqi forces launched a vast operation to retake Mosul eight months ago, seizing the city’s eastern side in January and starting an assault on the west the following month. It is not clear how many civilians have been killed in the operation.

Aid groups have raised concern that civilians could be caught in fierce street fighting. “UNICEF is extremely concerned about children who are being injured and killed in the escalating violence. Half of those being treated with bullet and shrapnel wounds in trauma centres in west Mosul are children,” Hawkins said.

Around 862,000 people have been displaced since the Mosul battle erupted. Around 195,000 have since returned, mainly to the city’s east. It was in the Old City’s emblematic Al Nuri Mosque in July 2014 that Daesh chief Abu Bakr Al Baghdadi made his only public appearance. He urged Muslims worldwide to move to the group’s “caliphate” straddling Iraq and Syria.

The extremists have since lost most of the territory they once controlled in the face of US-backed offensives in Iraq and in Syria, where a Kurdish-Arab alliance is advancing on their last major stronghold Raqqa.

On the political side, Iraqi Prime Minister Haider al-Abadi arrived in Kuwait on Wednesday (June 21) to meet with the country’s officials. According to a statement by Abadi’s press office, the Iraqi premier was officially welcomed by officials from Kuwait.

“Arrived in our dear neighbor Kuwait to discuss strengthening ties, increasing bilateral trade, investments, energy and security cooperation,” Abadi tweeted from his official account. Kuwaiti Prime Minister Jaber Al-Mubarak Al-Hamad Al-Sabah praised the relations between Iraq and Kuwait as two neighboring countries, the statement from Abadi’s office said.

Abadi is also scheduled to meet with the Emir of Kuwait, Jaber Al-Ahmad Al-Sabah, on Wednesday evening. Abadi’s visit followed stopovers to Saudi Arabia and Iran over the past few days. During his visit to Tehran, Abadi met with Iran’s Supreme Leader Ayatollah Ali Khamenei, who urged Abadi not to trust the United States in the war against the Islamic State (ISIS).

Khamenei also said that any measures to weaken Shia militias would endanger Iraq’s stability, while also expressed Iran’s support to Iraq’s unity and territorial integrity.
