As reported, the Ukrainian heavy-duty search and rescue team passed external recertification in accordance with INSARAG requirements in Gdansk, Poland.

It is now an international global network of managers, officials, and non-governmental organizations united to address the consequences of major disasters worldwide. Head of the Ukrainian team, Maksym Mayevsky, added that our team consists of 67 core members and 67 reserve members.
