THERE are “tens, maybe hundreds” of headless bodies lying in the bloody streets of a besieged Syrian border town — left to rot by ISIS savages to terrorise Kurdish fighters and residents, according to a new report.

“I have seen tens, maybe hundreds, of bodies with their heads cut off. Others with just their hands or legs missing. I have seen faces with their eyes or tongues cut out — I can never forget it for as long as I live,” Amin Fajar, a 38-year-old father of four, told the Daily Mail about the incredible scene in Kobani.

“They put the heads on display to scare us all.”

Another resident, 13-year-old Dillyar, watched as his cousin Mohammed, 20, was captured and beheaded by the black-clad jihadis as the pair tried to flee the battle-scarred town.

“They pushed him to the ground and sawed his head off, shouting, ‘Allahu Akbar,’ ” the boy said. “I see it in my dreams every night and every morning I wake up and remember everything.”

Farmer Ahmed Bakki said his cousin, a father of seven, stayed behind when his terrified family fled.

“We phoned my cousin and [ISIS] answered his phone. They said, ‘We’ve got his head, and we’re taking it,’ ” Mr Bakki said, adding that the most brutal ISIS barbarians were European.

“They are Chechen, they are English, they are from all over Europe. We know because we can hear their accent,” he told the paper after escaping to a refugee camp in Turkey.

The UK’s foreign secretary, meanwhile, said that boots on the ground are the only way ISIS militants can be defeated — but, like his US counterpart, he ruled out sending troops from his own country.

“The coalition can only deliver effective support to the Iraqi government and Iraqi security forces,” Phillip Hammond told reporters in Baghdad.

“The Iraqi people, the Iraqi security forces and Iraqi government will have to take the lead on the ground.”

His comments echoed those of Secretary of State John Kerry, who has repeatedly said it is up to the Iraqis to retake parts of their country captured by ISIS.

President Barack Obama on Tuesday expressed grave concern over the plight of Kobani and said a US-led coalition would keep up bombing raids there and in western Iraq.

“We’re deeply concerned about the situation in and around the Syrian town of Kobani,” Obama said after meeting commanders from countries in the coalition fighting the IS group.

The US leader said they were “also focused on the fighting that is taking place in Iraq’s Anbar province.”

Provincial leaders said Islamic State now controlled 80 per cent of Anbar.

The militants have fought fierce battles outside Baghdad and captured numerous towns to the city’s north, west and south, but lack the strength to capture the Iraqi capital, sources told The New York Post.

“They don’t have the manpower or the firepower despite what people may think. If they were going to make a move with their troops, we would have seen something by now,” one source said.

US Army Chief of Staff Gen. Ray Odierno said Monday he is “somewhat” confident that the Iraqi army can defend Baghdad.

“I believe the capability is there to defend Baghdad ... but we’ll have to see what plays out over the coming days,” he said.
