Sounds like Ukraine is sending a message and has the troops to back it up.
"LONDON, Oct 4 (Reuters) - Belarusian President Alexander Lukashenko accused neighbouring Ukraine on Tuesday of sending 15,000 troops to the border area to build defences and conduct reconnaissance, actions that he called "provocations".
Lukashenko allowed his close ally Russia in February to use Belarus as a staging post for its invasion of Ukraine. However, he has said Belarus is not a party to the conflict and that its own forces are not involved.
In comments carried by the state news agency BelTA, Lukashenko said the Ukrainian unit brought up to the border had blocked roads and was setting up checkpoints and firing positions.
"In a word, [Ukraine] has not only barricaded itself, but built a wall. Constantly conducting optical, radio-electronic and radio-technical reconnaissance of our territory, troops and objects," Lukashenko said.
"Often with their drones violating the line of the state border. And at the same time, they worry and worry: 'Oh, don't let Belarus enter the war'. And there are constant provocations at the border."
