Northern Italy has been hit by another deadly earthquake, a week after a quake in the region killed seven people.
The Associated Press said the bodies of two factory workers were found in a collapsed building, raising the earlier death toll of 15 to at least 17 as rescue efforts continued in the quake-hit Emilia-Romagna region.
Reuters reported that at least 200 were injured and seven people were still missing.
The quake registered a magnitude 5.8, according to Australia's ABC.
The dead included four people in Mirandola, BBC News reported. Three deaths were reported in San Felice and one in Cavezzo.
Citing the US Geological Survey, the ABC reported that the quake hit at 7 a.m. 24 miles northwest of Bologna and less than 19 miles from Modena, at a depth of 6 miles.
People ran out into the streets from shops and offices in Milan, Bologna and the Aosta Valley, close to the French border, while in Pisa — home of the iconic leaning tower — offices were evacuated. There have been several aftershocks since the early morning, BBC News reported.
Britain's Daily Mail cited Italian media as reporting that earthquake caused more buildings to collapse in the areas already affected by the 6.0-magnitude May 20 quake, where thousands were still sleeping outdoors in tents.
