Ukrainian Emergencies Minister Volodymyr Shandra has said he fears that another round of explosions might be heard at the 61st ammunition depot of the South Operations Command of the Ukrainian Land Forces in the town of Lozova, Kharkiv region, the ministry's press service reported on Saturday.

"If servicemen do not eliminate the threat by summer, the situation could happen again. Ammunition will again explode after it is heated by the sun," he said.

"We have done all that depends on us. A 500-meter security zone has been formed around the ammunition depot. However, the threat has yet to be eliminated inside the army unit itself," Shandra said.

As reported, a fire caused ammunition to explode at an arms depot outside Lozova on August 27, 2008. Locals have been then evacuated. The depot contains over 90,000 tonnes of ammunition.
