Two people have been killed and four others wounded after a rocket engine exploded during a test at a military base in Russia.
Moscow’s defence ministry said the blast occurred during the testing of a missile engine unit, causing a fire at a military shooting range in the northwestern Arkhangelsk region.
The ministry confirmed a total of six servicemen and civilian engineers were injured, and two later died of their injuries.
It said radiation levels were normal after the explosion, which involved a liquid-propellant rocket engine. No toxic substances were released into the atmosphere, the ministry added.
However, regional authorities later said they registered a short-term spike in the radiation level after the explosion.
It came two days after 16,500 people were forced to flee their homes when massive blasts rocked an arms depot in Siberia.
Powerful explosions continued for about 16 hours, killing one person, injuring another 13.
