Christians are disguising themselves by borrowing hijabs to escape the ISIS militants holding 1,500 people hostage in a besieged Philippines town.

More than three weeks after Islamist militants stormed the southern Filipino town of Marawi, starving locals are said to have resorted to extreme measures including eating their blankets to stay alive.

The civilians trapped in battle-torn neighbourhoods are being driven to daring escapes by the threat of capture, starvation and bombing by the military.

Five police officers and five Christian civilians dashed across the town's commercial district this morning, ducking for cover from a sniper, to reach a government-controlled area on the Agus River western bank.

'We ran the last part,' said First Officer Lumna Lidasan, 44. 'We could see the bridge ahead of us. We had to take cover several times when we saw a sniper.'

Almost the entire population of more than 200,000 fled after May 23, when fighters from local groups allied to ISIS rampaged through the Muslim-majority town, killing and kidnapping Christians.

The military estimates that, as the siege enters its fourth week, between 300 and 600 civilians are still trapped or being held as human shields in neighbourhoods occupied by the militants.

The insurgents have been suppressing government troops with skilled snipers, rocket-propelled grenades and high-velocity assault weapons, according to Philippine army officials.

Those stuck in their homes have no running water or electricity and many are near starvation, said Zia Alonto Adiong, a local politician managing rescue and relief efforts.

He said that in a text message pleading for help, one family said they had 'started to eat their blankets'.

'They are crossing the bridge, taking the risk, because they don't have any option - either they die inside the house or they die getting out,' he told reporters on Monday.

At least 100 people have made their way out on foot, braving volleys of sniper fire, said Adiong. Others have swum across the river or town-side lake to safety, according to relief workers.

Doctors treating those who escaped say they have been struck by the resilience of people who spent weeks surviving in a conflict zone and witnessing horrific violence.

'Some of the stories that stuck were Muslims helping protect Christian workers by letting them borrow a hijab,' said Dr Gioia Ancheta, head of the psychosocial therapy team.

As they approached the bridge on Tuesday morning, officer Lidasan could see troops waiting on the other side.

Terrified, but realising there was no turning back, the police officers and the Christians they had protected for three weeks, raced across the 25m stretch with no cover from snipers nesting in the town's tall buildings.

THOUSANDS OF CHILDREN STRANDED IN PHILIPPINES International children's charity World Vision has warned thousands of children have been left shell-shocked and traumatised by continuous fighting in the Philippines city of Marawi. The charity's humanitarian experts say over 100,000 children have been displaced by the conflict that has been raging on for more than two weeks. Thousands of them are paying a heavy price due to the unrest, with many now needing psychological first aid after experiencing and witnessing alarming levels of violence. Six-year-old Princess had been looking forward to her school opening again but that day now seems a long way off. More than 100,000 children, including six-year-old Princess (pictured), have been displaced by the conflict that has been raging on for more than two weeks Princess had been looking forward to her school opening again but that day now seems a long way off 'I was hoping to see my friends and my favorite teacher,' she said. 'I'm sad that I can't go back to school,' she added as she sketched the home she and her family were forced to leave. Meanwhile Rosela told of how here two-year-old daughter Mercy cried every times she heard gunshots and explosions. She went on: 'Life is not easy here but I'm glad were all alive. I don't want to go back to Marawi yet. 'I'm afraid that the conflict will happen again and I don't want my children to go through the same experience.' Ligaya Munez, World Vision's Programmes Manager in Mindanao, said they are setting up child-friendly spaces to provide psychological first aid to children affected by the crisis. Thousands of children have been left shell-shocked by continuous fighting in Marawi, including Mercy (pictured) who cries every time she hears gunshots She added: 'We've been going around evacuation centres and we've seen the struggles of the displaced children. 'We hope that through CFS, we can somehow give a sense of normalcy to the children. 'Aside from the humid environment and being unable to go to school, some children are still in shock from the gunshots and loud explosions they heard in Marawi.' Advertisement

'We don't think about ourselves, we think about the safety of the civilians,' said Lidasan, tears welling in his eyes as he recounted the story to reporters later.

Of the five Christians, who were in Marawi on a construction job when the crisis began, one was shot in the leg by sniper fire on Monday night as the group began their escape. Others were injured by cement kicked up by bullets.

'We crawled because snipers were shooting at us. I was wounded by splinters of cement hit by sniper bullets,' said Mateo Velasquez, 33.

'My belt bag was hit by a bullet. I thank the money, the coins hit by the bullet.'

The ten men had been trapped since the siege began in a bungalow with its own cellar.

They had basic supplies of dried noodles, canned goods and rice, but had to make a regular 'suicide mission' to find water, said Lidasan.

Militants patrolled nearby but they managed to stay hidden until they made their dash for freedom.

Most of those in a larger group of 18 civilians were not so lucky, according to a report from the military on Tuesday.

Militants knocked on the door of a house where they were hunkered down, prompting them all to flee through the back door and head towards the river.

'The terrorists ran after them and indiscriminately fired at them, killing five of the civilians and taking the remaining eight as hostages,' it said.
