Belarus says it downed Ukraine air defence missile

It happened during one of Russia's heaviest aerial onslaughts against Ukraine so far.

Footage from Belarusian state television appeared to show missile debris in a field, Qazet.az reports.

A Ukrainian military spokesman said the incident was "the result of air defence".

Belarus - a key ally of Russia - demanded that Kyiv carry out a full investigation, after the S-300 rocket came down near the border.

It is the first time Belarus has shot down a Ukraine missile since the Russian invasion in February.

The Ukrainian ambassador was called in to the foreign ministry in Minsk.

"The Belarusian side views this incident as extremely serious," spokesperson Anatoly Glaz told the Reuters news agency.

He called on Ukraine to "take comprehensive measures to prevent the recurrence of such incidents in the future".

Ukraine's defence ministry said it was ready to invite experts from countries that do not support "the terrorist state of Russia" to help investigate of the incident, adding that it reserved "the unconditional right to the defence and protection of its own sky". 

It said it did not rule out a "deliberate provocation" in which Moscow launched its cruise missiles on a path where they would be intercepted over Belarusian territory.
