MIRATOVAC, Serbia — Exhausted migrants by the thousands, some pushed in wheelchairs or on wheelbarrows, others hobbling on crutches or carrying young children, crossed on foot from Macedonia into Serbia on Monday as they sought to reach Western Europe.
The rush over the border by the migrants fleeing war and poverty in the Middle East and Africa followed Macedonia’s decision to lift the blockade of its border with Greece, after thousands stormed past Macedonian police who tried to stop their entry by force.
Nearly 10,000 people, including many women with babies and small children mostly from Syria, crossed into Serbia over the weekend.
Hundreds more entered Macedonia from Greece on Monday, as scuffles broke out between the migrants and police, who sought to stem the flow by letting in only small groups at a time. A pregnant migrant from Aleppo, Syria, was slightly injured in the scuffle.
The new surge of migrants has worried EU politicians and left the impoverished Balkan countries struggling to cope with the humanitarian crisis.
Visiting Macedonia on Monday, Austrian Foreign Minister Sebastian Kurz talked to migrants and shook hands with them. He also said Greece needed to control its borders more effectively.
“This is a humanitarian disaster. This is a real disaster for the whole European Union and I think there is the real need to have more focus on this problem, not only on the route through Italy but also on the route on the Western Balkans,” Kurz said.
In Austria, police said 37 people were injured — seven seriously — when two vans packed with migrants collided Monday near the Hungarian border. Dozens more migrants fled, along with the suspected smugglers.
After entering Serbia, the migrants head toward EU-member Hungary, from where they want to try to reach richer EU countries, such as Germany and Sweden.
After they formally ask for asylum, migrants have three days to reach the border with Hungary which is rushing to build a barbed wire fence on its border with Serbia to block them.
Late Monday, thousands boarded buses and trains that took them to Serbia’s northern border with Hungary, where they will try to enter Hungary illegally.
