Three people have been killed and 45 injured following an attack by Ukraine on a factory in the city of Izhevsk - more than 1,000km from the border. Of those injured six had suffered serious injuries, the governor of Udmurtia, Aleksandr Brechalov said. They had briefed President Vladimir Putin on the attack. A state of emergency was later declared in the region. Drones reportedly targeted the Kupol Electromechanical Plant - a military factory which is said to produce Tor surface-to-air missile systems and radar stations. The plant also specialises in the production of Osa air defence systems and has developed drones, according to Ukrainian media. A Ukrainian official confirmed that two long-range drones operated by the Security Service of Ukraine (SBU) struck the Kupol plant from a distance of around 1,300 km.
Russia's civil aviation regulator Rosaviatsia imposed restrictions on operations at Izhevsk airport, before lifting them a few hours later.
In a separate development on Tuesday, President Putin and his French counterpart Emmanuel Macron held their first phone talks in more than two years.
Macron "emphasised France's unwavering support for Ukraine's sovereignty and territorial integrity", said a statement from his office. The French leader also called for a ceasefire and negotiations between Ukraine and Russia "for a solid and lasting settlement of the conflict", the French statement said.
Meanwhile, a Kremlin statement said that Putin "reminded that the Ukrainian conflict is a direct consequence of the policy of Western states, who for many years ignored Russia's security interests".
