Polish President Andrzej Duda met today, Thursday, with NATO's secretary-general Jens Stoltenberg, in Brussels, and called for NATO to boost the readiness and size of its forces on its eastern flank.

For his part, Stoltenberg said that Poland is dealing with the migration crisis at its borders on its own without the direct support from NATO, adding that the allies are standing in solidarity with Poland and are ready to consider providing support if Poland requests it.

Earlier, the Chief of Staff of the Belarusian Army Viktor Golevich said that next year the army plans to increase the pace of combat training, develop reconnaissance and intelligence activity to "prevent a surprise attack" on his country.
