The roof of a building under construction collapsed, killing two workers and injuring seven others.
The building of the Hotel and Tourism High School, on the outskirts of the capital, Tirana, was undergoing renovation when the accident occurred, police spokesman Tefik Sulejmani said.
Rescue workers pulled two men from the rubble Isuf Spahiu, 55, and Anton Marku, 18.
Authorities were investigating, and detained for questioning some managers of Theos company, which was in charge of the renovation work.
The discovery of the submarine has unveiled a few "inconsistencies." For example, how can one explain the fact that the sub was found where it needed to be searched for from the start?
