Noting that almost half a million people have fled Mosul since the start of military operations to retake the city from Islamic State of Iraq and the Levant (ISIL/Da'esh) terrorists, a senior United Nations humanitarian official in Iraq warned that the scale of the displacement has stretched relief efforts to their "operational limits".

"The troops controlled the group's network of tunnels, in the South of the city, that is used as an alternative headquarters by the leaders", he added.
"The Daesh terrorist gangs tried to block the advance of our forces by using shells filled with toxic chemical material, but the effect was limited", Iraq's Joint Operations Command said in a statement, using an Arabic acronym for IS.
The battle for western Mosul is very different from the one in the east and so is the consequent impact on civilians.
