Turkish Prime Minister Ahmet Davutoglu Wednesday slammed as "hypocritical" calls by some countries urging Ankara to open its borders to Syrian refugees while failing to demand Russia stops its air strikes.

"I find it hypocritical that some circles are telling Turkey to 'open your borders' while at the same time failing to tell Russia 'enough is enough'," Davutoglu said after talks with his Dutch counterpart, referring to the Russia-backed assault by the Syrian regime on northern Aleppo.
