A Memorial Wall will be unveiled in Moscow on August 8th to commemorate the victims of a terrorist act that shook Pushkin's Square in the centre of Moscow on the same day two years ago. The explosion in the underpass killed thirteen and wounded 118 people, including six children.
The investigation revealed that an explosive equivalent to 800 grams of TNT two unknown people had left in a case near a shop in the underpass went off then. The criminals have not been exposed so far.
The Memorial Wall with the names of the victims engraved on it will be unveiled in the underpass, at the site of the explosion.
The choice of the city of Helsinki is not incidental as the capital of Finland had hosted US-Soviet negotiations on the limitation of nuclear stockpiles in 1969
