Some 350 to 400 migrants, including women and children, gathered at Bosnia's north-eastern border crossing to neighboring Croatia, Border Police spokesperson Sanela Dujkovic said on Wednesday.

A small incident occurred when police officers prevented two migrants from crossing into the EU country, but nobody was injured.

“The situation is becoming complicated due to the number of migrants, as this was first a group of 70-80 migrants,” Dujkovic said of the crossing near Bosnia’s northeastern-most town of Velika Kladusa.

There have been no urgent medical interventions or major incidents until now, she said.

Another group of some 130 to 150 migrants who were found about a kilometre away from the Western Izacic border crossing was taken back to migrant centres in Bihac from where they departed a day earlier, Dujkovic said.

Croatia’s Interior Ministry earlier said that its police is committed to implementing the national and European laws and prevent any illegal crossings of their state border, which is also the EU border.

“False information saying that Croatia will allow their arrival in its territory and their further transit toward Western European countries is being spread among the migrants currently on the territory of Bosnia and Herzegovina and Serbia,” Croatia’s ministry said.
