A increasingly paranoid Vladimir Putin has imposed a massive secutiry clampdown on Moscow ahead this week's huge annual Victory Day parade.

The move comes amid an overnight strike on the city’s "Hollywood" district when an elite high-rise tower in Mosfilmovskaya Street was hit and damaged by a Ukrainian drone. The attack on the high-rise building - rumoured to be home to key figures in Russia’s SVR foreign intelligence service - was by an unmanned plane which evaded sophisticated air defences installations in the city.
