Poland's foreign minister says his country has evidence that Russia recruited people on the Telegram messaging service to carry out last year's massive shopping centre fire in Warsaw. Speaking to the BBC in an exclusive interview, Radek Sikorski said Moscow's actions were "completely unacceptable" and that a second Russian consulate in Poland had been closed as a result. His comments come after a Polish investigation concluded that the Marywilska shopping centre fire was orchestrated by Moscow's intelligence services. Russia denied its involvement, with Kremlin spokesman Dmitry Peskov accusing Poland of being "Russophobic".
