ANOTHER powerful earthquake has shaken Italy, damaging homes, businesses and ancient buildings.
Sunday's quake with a preliminary magnitude of 6.6 was the strongest to strike the country in nearly 36 years, hitting a mountainous region north-east of Rome where people were still unnerved after a pair of aftershocks last week and an August quake that killed nearly 300.
There were no immediate reports of deaths. Around 20 people suffered minor injuries.
Premier Matteo Renzi pledged to rebuild the wrecked churches and buidlings, saying they were part of Italy's national identity. The government last week earmarked 40 million euros (£36m) for rebuilding.
"We will rebuild everything," Mr Renzi said. "We are dealing with marvellous territories, territories of beauty."
Residents already rattled by a constant trembling of the earth rushed into the streets after being roused from bed by the early morning quake. It was felt as far north as Salzburg, Austria, and all the way down the Italian peninsula to the Puglia region, the heel of the boot.
"It is not since 1980 that we have had to deal with an earthquake of this magnitude," said Fabrizio Curcio, head of Italy's Civil Protection agency. He was referring to a 6.9-magnitude quake near Naples that killed some 3,000 people and caused extensive damage in November 1980.
He said authorities were responding with helicopters to help the injured and monitor collapses, as many roads were blocked by landslides. Some 3,600 people had already been relocated, many to the coast, following last week's quake, and Mr Curcio said more would follow.
Closest to the epicentre was the ancient city of Norcia, the birthplace of St Benedict, the father of monasticism, and famed for its Benedictine monastery.
Witnesses said the 14th century St Benedict Cathedral collapsed in the quake, with only the facade still standing.
"It's as if the whole city fell down," Norcia City Assessor Giuseppina Perla told the ANSA news agency. The city's ancient walls suffered damage, as did another famous Norcia church, St Mary Argentea, known for its 15th century frescoes.
Television images showed nuns rushing into the main piazza as the bell tower appeared on the verge of collapse. Later, nuns and monks knelt in prayer in the main piazza. A firefighter appealed to a priest to help keep residents calm in an effort to prevent them from looking for loved ones.
The town's deputy mayor, Pierluigi Altavilla, said his house remained standing, but everything inside had been toppled.
"It seemed like a bomb exploded inside the house," he told Sky TG24.
The quake comes during a long holiday weekend in Italy ahead of Tuesday's All Saint's Day, when Catholics remember the dead. The head of the church in Umbria, Cardinal Gualtiero Bassetti, urged priests not to hold Masses inside churches but in open spaces for fear of further collapses, ANSA reported.
Mayors in some towns, including Castelsantangelo sul Nera, said coffins had been pushed out of their resting place inside cemeteries, which in Italy are typically walled structures.
"The scene is indescribable," Mayor Mauro Falcucci told ANSA.
The quake struck a cluster of mountain towns, many of historic significance, already reeling from last week's pair of aftershocks to last August's deadly quake, including Norcia, Visso, Castelsantangelo sul Nero and Preci.
Some towns and smaller settlements were left isolated by landslides that blocked the roads, and the civil protection authority was responding with helicopters to help the injured, while also monitoring damage.
A civil protection official in the Marche region, Cesare Spuri, said authorities were trying to determine if people were trapped under debris. New collapses were also reported throughout the region, including in Tolentino, where three people were extracted from the rubble.
The hilltop town of Camerino suffered new building collapses, but there were no reports of injuries.
The mayor of Ussita said a huge cloud of smoke erupted from the crumbled buildings.
"It's a disaster, a disaster" Mayor Marco Rinaldi told ANSA. "I was sleeping in the car and I saw hell."
In Arquata del Tronto, which had been devastated by the deadly August earthquake, Mayor Aleandro Petrucci said, "There are no towns left."
"Everything came down," he said.
The Salaria road, one of the main highways in the region, was closed at certain points. In addition, Italy's rail line said some local lines in Umbria and Le Marche were closed as a precaution.
The quake forced the temporary closure of some of Rome's most important tourist sites, including the presidential palace, so authorities could check for damage.
The St Paul Outside the Walls basilica was closed for several hours after some plaster fell, but was later reopened. Vatican firefighters conducted checks at St Peter's Basilica and the Vatican's other basilicas but found no damage.
The crowds in St Peter's Square interrupted Pope Francis with applause when he mentioned the quake during his weekly Sunday blessing.
"I'm praying for the injured and the families who have suffered the most damage, as well as for rescue and first aid workers," he said.
