Masked revelers in colorful hand-made costumes thronged the streets of Pernik in Bulgaria on Sunday, warding off evil spirits and celebrating the beginning of spring with hopes for good health and a good harvest, reports Reuters. 

A 15-strong team from the National Investigative Service is to have access to the area where an explosion demolished an ammunition factory in Bulgaria's north-west, killing 15 people.

This is the first time anyone, except for a fire-brigade unit using special equipment, will enter the site after the 24-hour ban was lifted on Thursday, 21:00 EEST (19:00 GMT).

It was the debilitation of Bulgarian Interior Ministry that led to Friday's tragedy in the town of Lyaskovets .

These comments were made for Bulgarian National Television by the expert Tihomir Bezlov from the Center for the Study of Democracy.
