According to police data, 2,093 migrants were detained Monday, the highest figure so far this year. Over the past week, the daily average was of 1,493 migrants.
The surge comes after nearly 10,000 people, including many women with babies and small children mostly from Syria, rushed across the Macedonian border into Serbia over the weekend.
Another 1,000 arrived in Serbia Tuesday morning and their next stop is most likely to be EU-member Hungary.
