William Spindler, spokesman of the U.N. High Commissioner for Refugees (UNHCR), said the agency understood the concern of Turkish authorities about "possible large influxes" into the country, already hosting more than 2.5 million Syrian refugees, according to Reuters.

"Turkey has also allowed a number of vulnerable and wounded people in Turkey. However, many people are not being allowed to cross the border. We are asking Turkey to open its border to all civilians in Syria fleeing danger in need of international protection as they have done," Spindler told a news briefing.
