A 5.6-magnitude earthquake has shaken central Albania, injuring dozens of people and damaging buildings.

The government said it was the most powerful quake to hit the Balkan country in nearly 30 years.

The earthquake struck west of the capital, Tirana, just after 4 p.m. local time on Saturday.

According to the US Geological Survey, its epicenter was near the coastal city of Durres and about 10 kilometers (6 miles) deep.

Local media reported that around 68 people had been taken to hospital, mostly with minor injuries.

The jolt, which triggered power cuts in Tirana and caused buildings to collapse in some towns, was followed by a strong aftershock.

“All our neighbors came out screaming. Thank God it did not last long — about 20 seconds. It was a nightmare on the 10th floor. I don’t remember a more powerful one than this,” a Tirana resident told.

Health Minister Ogerta Manastirliu said 68 people had been treated for injuries in Tirana and Durres. Most were hurt while dashing out of their homes in panic.

Many of them have been discharged after treatment, she said.

“Fewer people are coming to the hospitals,” Manastirliu told reporters.

In the region of Tirana, 48 houses and three apartment buildings had suffered cracks, while in Durres region 42 houses and four apartment buildings were damaged, Defence Minister Olta Xhacka told.
