Croatian riot police have clashed with migrants seeking to enter the country from across the Bosnian border, Reuters reported on Wednesday.

Earlier in the day, hundreds of migrants broke a Bosnian police cordon and blocked the Maljevac border checkpoint in northwestern Bosnia in a bid to pressure Croatian authorities into allowing them clear path towards Western EU countries through Croatia.

They reportedly shouted “Open borders!” hurling stones at Croatian police, who responded with teargas and baton charges, leaving several people injured. A woman sustained head injuries during the clash and was rushed to hospital alongside another injured man.

According to Bosnian media, the migrants had spent two nights sleeping some 100 meters from the border crossing, hoping to be allowed into Croatia. They warmed themselves next to campfires and set up improvised tents to spend cold nights.
