Two new earthquakes hit northern Italy on Tuesday. The two aftershocks, one of 5.3 and one of 5.1 magnitude, came as a 5.8 magnitude hit the area three hours earlier. At least 15 people have been killed.

Most deaths were caused by the first earthquake. It shook the area just after 9am local time bringing down buildings already damaged by a quake that hit the area less than two weeks ago and killed seven people.

In Mirandola, 25 miles (40km) north-west of Bologna, identified as the epicenter of the earthquake, rescue workers searched the ruins of an industrial building that collapsed looking for a missing worker.

The earthquake was felt throughout northern Italy and buildings were evacuated in Genoa and in Pisa.

Many houses near the epicentre of the first quake were left with large cracks. After the initial earthquake earlier this month at least 5,000 people were made temporarily homeless and put in makeshift tents
