 Belarus fears that the Ukrainian army may enter its territory. In Belarus, a line of anti-tank fortifications, the so-called Dragon's Teeth, appeared near the border with Ukraine. Belarusky Hajun Monitoring Project reported it. It is reported that the line of Dragon's Teeth is located 10 km from Homil, near the M18 highway towards the border with Ukraine. In addition, construction of what are presumably fortifications is ongoing very close to the border as well. It should be noted that Belarus has served as a springboard for Russia's war against Ukraine from the outset. Russian forces invaded Ukraine from Belarus, despite prior assurances by top Belarusian officials that this would not happen and the country has continuously provided logistical support, supply lines, and medical care for Russian soldiers. Russian military aircraft have also used Belarusian airfields. Russia has also been moving scores of weapons and other military equipment in and out of Belarus. Among the units remaining in Belarus are S-400 air defense and Iskander and top M2 missile systems as well as fighter jets and other military aircraft including the MiG-31K fitted with Kinzel missiles. Yet such military posturing by Belarus has compelled Ukraine to watch its northern neighbor closely. Ukrainian forces have fortified and mined territory close to Belarus and blown up some bridges. Rather than concentrating all its forces in the east and south of the country, Ukraine has kept around 20,000 troops along the Belarusian border. Belarus fears that the Ukrainian army may enter its territory.
