June 22nd, 2017- RTP begins a mission to evacuate women and children caught in the cross-fire on Monsul's front line.  Each day, Sally and her team drive back and forth to the old city, collecting the families who are too exhausted to continue on foot and transporting the injured to the trauma stabilisation point where a team of doctors and medics from Cadus and Road to Peace help to stabilise the children before sending them to hospitals on the outskirts of the city.

What is clear is that these are the dying days of so-called Islamic State in Mosul. We have witnessed a clear change in the tempo of military operations since IS blew up the famed al-Nuri mosque last Wednesday. 

The push against the militants has gained momentum - with increased ground operations and air strikes. 

We counted about 20 air strikes through the day on Sunday, with helicopter gunships pounding IS targets and a great deal of mortar fire. 

IS fighters are pinned down in a corner of the Old City, where the narrow streets favour the insurgents. The Iraqis believe the numbers are relatively small - about 300 to 450 - but these are battle hardened jihadists, most of them foreign. IS still has the capacity to resist. 

Iraq's Emergency Response forces told us they had recently faced 80 suicide bombers in a four-day period. Counter-attacks by IS involving suicide bombers last night were dealt with swiftly, but the militants are fighting to the finish.

Tens of thousands of civilians are believed to remain trapped in the Old City. 

As for the number of IS fighters still there, estimates from the Iraqi military and analysts suggest several hundred.

'We were just a couple of streets away from one of the IS counter-attacks.

We had about 20 bodies (Iraqi soldiers) here yesterday and many more injured. In fact the trauma stabilisation point (TSP) is full of soldiers right now. An officer arrived with a bullet in his neck yesterday afternoon and shortly after that everything went a bit crazy. 

There were cars set alight and roads were closed.

According to sources here, about 20 jihadists had escaped from within he Old City and popped up a couple of blocks from our TSP. In addition to this, the jihadist snipers have night vision goggles which meant the Iraqi army could only move very slowly.

It's definitely calmed down a bit now, although between about five and seven this morning it was pretty full on.'

July 11th, 2017 - Dr Marino Andolina, a volunteer with Road to Peace, has treated over a thousand children in the past three weeks. "Left... malnourished, without even a name" – these children are orphans of the battle for Mosul.

May 9th, 2017 - Following the success of our mobile clinic operating in the streets of Mosul, we expand the scope of the initiative to include treatment for some of our patients in a trauma stabilisation unit together with the Iraqi army, a team from DAMA and German NGO Cadus.

March 29th 2017 - Children are being killed or seriously injured as Iraqi forces battle Islamic State militants in heavily populated areas of Mosul, but the battle to retake the city - where 350,000 children are trapped - is far from over, and the heaviest fighting is still ahead. Road to Peace are operating a mobile clinic in the West side of the city where health care is minimal and many children have not seen a doctor for over two years.
