Truckers angered by days of waiting at the Croatian border with Serbia late on September 22 blocked all traffic on the largest highway between the two countries.

Serbian state TV RTS showed drivers blocking the main Belgrade-Zagreb highway at the border a few hours after Croatian authorities partially lifted a ban on all cargo traffic that they imposed on September 21.

Frustrated drivers parked several trucks across the main Bajakovo-Batrovci crossing in no-man's land, halting all road traffic.

"We had to do it," said a driver from the Serbian town of Novi Pazar who gave his name as Emin. "We've been here for almost three days and no one even came to ask us whether we're hungry or thirsty or to bring us anything."

Also September 22, Belgrade activated the European Union's so-called civil protection mechanism, to which it has access as a membership candidate. In doing so, it will receive EU support to cope with the influx of refugees and asylum seekers

Serbia has asked for beds, mattresses, hygienic items, vehicles, fuel, and food.
