People hold photographs of late Polish President Lech Kaczynski as they take part in a silent march through the old city to the Wawel Royal Castle in Krakow
The Bulgarian Government has declared Sunday April 18 a national day of mourning to mark the death of Polish president Lech Kaczyński and his wife Maria, Bulgarian media reported on April 16 2010.
The Government has asked the nation to honour the Polish plane crash victims by abstaining from any social activities, gatherings and celebrations.
All Bulgarian flags on government institutions and municipal buildings will be lowered to half mast as a mark of respect to the victims of the crash and the people of Poland.
The president was killed when a government plane crashed near the airport of the Russian city of Smolensk on April 10 2010, killing everyone on board.
The Polish delegation was in Russia to mark the 70th anniversary of the Katyn massacre, when the Soviets killed thousands of Poles.
