Two US Air Force jets carried out strikes on the country's own ammo dumps in Syria on Wednesday amid fears the weapons could fall into the wrong hands, defense officials revealed.

The weapons had been left behind when US soldiers fled after Donald Trump decided to withdraw his forces from northern Syria during a phone call with Turkish President Recep Tayyip Erdogan on October 6.

Two F-15 jets were scrambled to blow up the storage bunker, located at the Lafarge Cement Factory between Kobanî and Ain Issa, amid fears the weapons could fall into the hands of armed groups, including Russia.

In a statement, US Army Colonel Myles Caggins told CNN said the jets 'successfully conducted a pre-planned precision airstrike' after all 'personnel and essential tactical equipment' had been removed from the site.

'On October 16, after all Coalition personnel and essential tactical equipment departed, two Coalition F-15Es successfully conducted a pre-planned precision airstrike at the Lafarge Cement Factory to destroy an ammunition cache, and reduce the facility's military usefulness', he said.

However, some politicians have attacked the president for his hasty decision.

Republican congressman Adam Kizinger, who represents Illinois, tweeted: 'We bombed our own base on purpose, because of the impulsive decision by @realDonaldTrump didn’t leave time to evacuate the right way. Is this the America you grew up believing in?'

It was said that no other forces had been near the site, which is close to the Turkish border, at the time.

Caggins also said on Tuesday that Kurdish-led forces had 'set fire to, then vacated, its facilities and equipment' when 'Turkish-backed militias advanced towards the Lafarge Cement Factory'.

On Sunday, Defense Secretary Mark Esper revealed the US planned to pull its remaining 1,000 troops out of northern Syria 'as safely and quickly as possible'.

There had been around 1,000 soldiers in the territory allied with the Kurdish-led Syrian Democratic Forces to combat ISIS. The Pentagon previously pulled about 30 of these troops from the Turkish attack zone along the border.

Defense Secretary Mark Esper said: 'It'll be a deliberate withdrawal, and we want to conduct it as safely and quickly as possible.'

Esper said he would not discuss a timeline for the US pullback, but said it would be done 'as safely and quickly as possible.'

A military source confirmed on Wednesday that US forces had been pulled from all locations across Syria and would meet at a location near Kobani, from which they will be airlifted away from the conflict within the next few weeks.

It comes after Russian journalists filmed themselves inside abandoned American bases that appeared to have been left largely intact, with writing still seen on white boards inside.
