There will be problems in the security sphere for a long time, which means we have to work harder and be ready for any scenario, Deputy Mayor of Yerevan Tigran Avinyan told reporters on Friday.

"Even in conditions of war and with security problems, life must go on and we must work even more intensively," he added.

Avinyan said that shelters have been cleaned up during the year.

"I can't say that the problem is completely solved, but the situation has improved significantly," the official noted.
