Iraqi troops advance on Islamic State-held Fallujah
Iraqi troops have pushed towards Fallujah from the south, aiming to completely surround the Islamic State-held city, Iraq's elite counter-terrorism forces said.
The operation to retake the town from the extremist Islamic State group was officially announced late on Sunday night.
"Our troops are now in the process of surrounding the city from all (sides)," said Lieutenant General Abdul-Wahab al-Saadi, the head of the counter-terrorism forces' Fallujah operation.
"By doing so, we will besiege the city of Fallujah in full. And then we will start storming the city from several directions with new forces."
Fallujah is 40 miles west of Baghdad.
Booby-trapped explosives and large numbers of civilians unable to escape are expected to complicate operations moving forward, Lt al-Saadi said.
The spiritual leader of Iraq's Shiites called on Iraqi forces battling to retake the city of Fallujah to protect civilians there.
Grand Ayatollah Ali al-Sistani said that "saving innocent people from harm's way is the most important thing, even more so than targeting the enemy".
His comments were delivered at Friday prayers by his representative, Ahmed al-Safi, in the holy city of Karbala.
Rights groups have expressed concerns for the tens of thousands of civilians estimated to still be in the city, which has been in IS hands for more than two years.
In the capital, Baghdad, Iraqi security forces fired tear gas and live ammunition to disperse thousands of anti-government protesters gathered in the city's Tahrir roundabout.
The protesters assembled despite calls earlier this week from Iraqi Prime Minister Haider al-Abadi to halt protests so the country's security forces could focus on the Fallujah operation.
