ROME (Reuters) - Enrico Letta was sworn in as Italy's new prime minister on Sunday and immediately faced an emergency after an unemployed man shot two police officers outside his office.
The 49-year-old gunman, from the poor southern region of Calabria, told investigators he had planned to attack politicians but had found none within range.
One of the officers was shot in the neck, hitting his spinal cord, and he was in a serious condition, surgeons said. The other was shot in the leg.

Newly elected Pope Francis, Cardinal Jorge Mario Bergoglio of Argentina, checks out of the church-run residence on March 14, where he had been staying in Rome. Pope Francis returned on Thursday to the Church-run residence where he was staying before becoming pontiff, and insisted on paying the bill, despite now effectively being in charge of the business, the Vatican said.

The Latin American pope’s election shattered Europe's centuries-old grip on the papacy, and his choice of name — in honor of the 12th century saint from Assisi — is widely seen as a nod to a new era of simplicity.
Lombardi said Pope Francis declined the official papal car for his first journey from the Sistine Chapel, choosing instead to board a bus with cardinals who had just elected him.
Later, at dinner, the new pope prompted laughter by responding to their toast with the remark: "May god forgive you for what you have done."
Francis returned Thursday to the church-run hostel where he had stayed ahead of the conclave and insisted on paying the bill.
"He was concerned about giving a good example of what priests and bishops should do," a Vatican spokesman said. He did not disclose how much the bill totaled. Read more.

In 2005, visitors packed into the expansive boulevard leading up to St. Peter’s Square as Pope John Paul II’s body was carried into the crowd for public viewing in the days following his death. Taken nearly two years before the iPhone debuted, the photo is striking now for its appearance straight out of another era.
For anyone who has ever been to a concert, the photo at bottom, taken Tuesday night as Pope Francis made his inaugural appearance on the Vatican balcony, seems almost ordinary. The two, taken together, reflect a world changing, even as some ancient traditions stay the same.

This combined picture shows Italian sculptor Oliviero Rainaldi's statue of Pope John Paul II before its restoration, left, on Sept. 23, 2011, and at its inauguration after the restoration, in Rome on Nov. 19, 2012.
The Associated Press reports — The city of Rome has inaugurated a revamped statue of Pope John Paul II after the first one was pilloried by the public and the Vatican.
Pope or Mussolini? Statue sparks uproar
Artist Oliviero Rainaldi says he's pleased with the final product, saying it matches his original vision. He blamed foundry workers for a botched assemblage the first time around.
The statue was restored after Rainaldi was pilloried by the Vatican for creating a sculpture of Pope John Paul II that some mockingly said looked more like Fascist dictator Benito Mussolini than the beloved late pontiff. Even the Vatican's own art critic wrote that it looked like a "bomb" had landed.

Alcoa workers clash with police near the Ministry of Economic Development in Rome on Sept. 10.
Workers from a threatened Alcoa Inc. aluminum plant in Sardinia clashed with police Monday as they continued a protest in Rome to pressure the Italian government to intervene to keep the factory open.
Reuters reports: U.S.-based Alcoa plans to close the loss-making factory by November unless a buyer is found. The only interested suitor, German hedge fund Aurelius, pulled out of talks with the government in August.
Closure of the plant, a major employer on Sardinia, would be a heavy blow for the island, risking hundreds of jobs in a region already beset by high unemployment and a sluggish economy.
