The arms store at a Russian military base in Crimea has been targeted with a series of explosions going off overnight. It’s not been a week since big blasts went off at another Russian base in Crimea, and this time Russia is blaming sabotage. A spokesman for Ukraine’s President Volodymyr Zelensky called it “demilitarisation in action”. Ukraine says it’s making progress – that includes a strike against the headquarters of a secretive paramilitary group after a Russian journalist unwittingly shared its address. The Wagner Group – which has long been accused of engaging in war crimes on Russia’s behalf – isn’t publicly acknowledged by the Kremlin. Reports say Ukraine used one of its US-made High Mobility Artillery Rocket Systems (HIMARS) in the attack. Analysts say that the long-range weapons system has given Ukraine an edge over Russia as it attempts to claw back territory in the country’s east.
