At least one person has been killed and six others injured in an explosion on a passenger bus in Armenia’s capital Yerevan.
The explosion took place on Halabyan street on the bus driving on its route on Monday night.
"The cause of the explosion is being inquired", Armenian Emergency Situations Ministry's Rescue Service chief Nikolai Grigoryan said.
Witnesses said the bus was gutted by the blast, which blew out the windows of nearby houses.
Security forces and employees of the National Crisis Management Center were working at the scene of the blast.
The explosion happened a day after Yerevan held ceremonies commemorating the 101st anniversary of the Armenian massacre during the World War I. Armenians believe that up to 1.5 million Armenian Christians were systematically slaughtered in eastern Turkey through mass killing, forced relocation and starvation, a process that began in 1915 and took place over several years during World War I and the breakup of the Ottoman Empire.
