Turkey's president has warned of imminent military offensives on two Kurdish-held areas in northern Syria, as tanks and troops mass on the border.

Recep Tayyip Erdogan said Syrian rebels would support Turkish efforts to clear the "terror nests" of Afrin and Manbij. 

The areas are controlled by the Kurdish People's Protection Units (YPG), which Ankara considers a terrorist group.

Earlier, the Turkish army shelled Afrin from positions in the neighbouring rebel-held Syrian province of Idlib. 

The Kurdish official in charge of defending the area, Bahjat Abdo, said the bombardment showed "the bankruptcy of Turkish policies in the face of resistance by the people of Afrin".
