A Turkish soldier has been killed amid sporadic clashes with Kurdish fighters in northern Syria, despite a US-brokered ceasefire, Turkey's defence ministry has said.
The ministry said the soldier was killed during an observation shift on Sunday, in an attack involving anti-tank weapons and small arms fire.
In a statement, the ministry said Syrian Kurdish fighters have violated the three-day-old truce around 20 times.
Commander of the Kurdish-led Syrian Democratic Forces, General Mazloum Abdi, says the Turks are violating the terms of the ceasefire "in front of American eyes".
It follows US Vice President Mike Pence's announcement, on Thursday, that he had secured a 120-hour cease-fire to allow Kurdish fighters to withdraw from a "safe-zone" along the border.
The death toll among Turkey's military during its wide-ranging offensive against Syrian Kurdish forces has now risen to seven.
Turkey's President Erdogan's threatened to "crush the heads" of Kurdish fighters unless they withdraw from the border.
Turkey considers the Syrian Kurdish groups terrorists for their links to a long-standing Kurdish insurgency inside Turkey.
The ministry also said it allowed a 39 vehicle humanitarian convoy to enter Ras al-Ayn, a key border town that has seen some of the heaviest fighting.
It said the convoy evacuated the wounded and others.
It has been reported that Britain has taken the first steps to repatriate children stranded in Syria.
It is believed officials are liaising with agencies on the ground to identify unaccompanied minors and secure them safe passage back to the UK.
