Yerevan - Armenians spent Sunday commemorating a devastating earthquake that left about 25,000 people dead on December 7, 1988.
The earthquake, which also left about 500,000 homeless, marked the first time that the Soviet Union - to which Armenia belonged in 1988 - allowed foreign aid workers to enter its territory.
As part of the day's ceremonies, President Serzh Sargsyan was expected to approve a memorial to the earthquake's victims in the town of Gyumri.
