Turkish and US-led coalition forces have killed around 27 Isis fighters north of the Syrian city of Aleppo, Turkish media reports.

The Turkish military fired artillery and rocket launchers into Syria while warplanes from the US-led coalition carried out three separate air campaigns on Saturday, the state-run Anadolu Agency reported Monday, citing military sources.

Five fortified defence posts and two gun posts were destroyed, while 27 fighters were killed in areas less than 10km (6.2 miles) from Turkey's border with Syria.

The fighters are reported to have been killed on the verge of firing rockets into Turkey.

Coalition and Turkish forces have recently carried out a series of such strikes to prevent further attacks on the Turkish border town of Kilis, which sits near Isis-controlled territory in Syria and has regularly been hit by rocket attacks in recent weeks.

So far, around 20 people have been killed and almost 70 wounded in rocket fire on Kilis.

Isis has recently suffered a series of military setbacks, including one of its biggest military defeats in Palmyra, which was seized by regime forces backed by Russian air strikes.

"This perverse caliphate is shrinking," the US envoy to the 66-member anti-Isis coalition said on Sunday.

Brett McGurk said the group has been forced to go on the defensive after losing control of their territory.

However, as Isis militants have been pushed back, the group is increasingly turning to terror attacks to keep pressure on the Iraqi government.

The terror group unleashed a wave of suicide attacks and car bombings which left more than 100 people dead in just 24 hours in Baghdad.
