Horror moment bomb lands metres away from man in Ukrainian city of Mykolaiv

Elsewhere, at least 35 people were killed in a Russian airstrike at a base where foreign instructors were helping Ukrainians just 12 miles from the Polish border.

Russian forces fired more than 30 cruise missiles at the Yavoriv military base near Lviv, injuring 134 people, according to Ukrainian authorities as Kyiv warns Vladimir Putin could start "provoking" Nato countries.

Foreign military instructors have worked at the Yavoriv International Centre for Peacekeeping and Security - but a Nato official said there were no personnel from the alliance at the base at the time of the strike.

Regional governor Maksym Kozytskyy said Russian planes fired around 30 rockets at the facility - with some were intercepted before they hit.

Witnesses reported seeing 19 ambulances with sirens on driving from the base's direction following the strike as black smoke rose from the area.
