The border service of Belarus and the country's Ministry of Defence are taking measures to further reinforce the Belarusian border with Ukraine after a security incident, the Belarusian border service said in a statement, Paralel.Az reports citing Reuters.

The border service said its staff had brought down a quadrocopter on Wednesday after it had illegally crossed the border from Ukraine to collect information about Belarusian border infrastructure.

Earlier in the week, it said materials for a homemade bomb had been found concealed in the same area and that it was aware that a unit of pro-Ukrainian Russian fighters was present in a Ukrainian region bordering Belarus.
