At least 10 people, including the gunman, were killed Tuesday at an adult education center in what Sweden’s prime minister called the country’s worst mass shooting. But a final death toll, a conclusive number of wounded and a motive hadn’t yet been determined hours later.

Prime Minister Ulf Kristersson gave a news conference in the aftermath of the tragedy, which happened on the outskirts of Orebro. The city is about 125 miles west of Stockholm.

The school, called Campus Risbergska, serves students over age 20, according to its website. Primary and upper secondary school courses are offered, as well as Swedish classes for immigrants, vocational training and programs for people with intellectual disabilities.

“Today, we have witnessed brutal, deadly violence against completely innocent people,” Kristersson told reporters in Stockholm. “This is the worst mass shooting in Swedish history. Many questions remain unanswered, and I cannot provide those answers either.

“But the time will come when we will know what happened, how it could occur, and what motives may have been behind it. Let us not speculate,” he said.

Justice Minister Gunnar Strömmer called the shooting “an event that shakes our entire society to its core.”

While Swedes read about such violence in other places, Strömmer said that the country previously felt it wouldn’t happen there. Other tragedies in Swedish schools weren’t to the extent of Tuesday’s attack, he said, calling it “indescribably sad” for the community.

The damage at the crime scene was so extensive that investigators were unable to be more definitive about the number of fatalities, said Roberto Eid Forest, head of the local police.

Police said that the death toll could rise. Eid Forest told reporters that the suspected gunman was among those killed. Police believe the perpetrator acted alone, and he wasn’t previously known to police, officials said.

Authorities said that there were no suspected connections to terrorism at this point, but police didn’t provide a motive.

USAID’s global workforce put on leave

Nearly the entire global workforce of the main American aid agency, known as USAID, will be put on administrative leave by the end of Friday, according to an official memo the agency posted online Tuesday night.

The notice said only a small subset of “designated personnel responsible for mission-critical functions, core leadership and specially designated programs” would be exempt.

Employees posted abroad will be expected to return to the United States within 30 days, the notice said, adding that the agency would “arrange and pay for return travel.”

The notice was posted on the agency’s website, which had been dark since Saturday. It stated that exceptions would be considered on a case-by-case basis, including for reasons of “personal or family hardship, mobility or safety concerns.”

About 10,000 people around the world work for the agency.

Greenland bans foreign political contributions

Greenland’s parliament passed a bill Tuesday that bans political parties from receiving contributions “from foreign or anonymous contributors” after President Donald Trump expressed his wish that the United States take over the vast and mineral-rich Arctic island that belongs to Denmark.

The bill is aimed at protecting “Greenland’s political integrity” and will take effect immediately, according to a translation of a parliamentary document in Danish outlining the measure.

The bill “must be seen in light of the geopolitical interests in Greenland and the current situation where representatives of an allied great power have expressed interest in taking over and controlling Greenland,” the document said.

Before taking office for his second term on Jan. 20, Trump said he would not rule out the use of military force to seize control of Greenland, calling it vital to U.S. national security.

Judge blocks prison transgender policy

A federal judge agreed Tuesday to temporarily block prison officials from transferring three incarcerated transgender women to men’s facilities and terminating their access to hormone therapy under an executive order signed by President Donald Trump.

U.S. District Judge Royce Lamberth in Washington, D.C., granted the inmates’ request for a temporary restraining order.

The judge is presiding over a lawsuit filed on be

half of three transgender women who were housed in women’s facilities before Trump signed the order on Jan. 20, his first day back in the White House.

USPS to block all packages from China

The U.S. Postal Service said that it would temporarily suspend the acceptance of inbound international packages from China and Hong Kong Posts until further notice.

USPS said letters and flat mail from China and Hong Kong would not be affected. The White House didn’t respond to a request for comment.

The move comes after President Donald Trump revoked a “de minimis” allowance that exempts small packages worth less than $800 from duties, used by Chinese-linked e-commerce companies, as part of the 10% tariff order placed on goods from China and Hong Kong issued just after midnight, Eastern time.

All CIA staffers offered buyouts

The Central Intelligence Agency has offered staff buyouts to shrink the workforce in line with the Trump administration’s broader job cuts across the government and to sharpen the spy service’s focus on top priorities like China.

As part of the offer sent to the workforce on Tuesday, employees could receive pay and benefits through Sept. 30, without having to work. It’s unclear how many will take the offer at the agency.

John Ratcliffe, President Donald Trump’s nominee to lead the CIA, promised in his Senate confirmation hearing to focus on the threats posed by China and expand the volume of intelligence that officers collect around the world.

“Director Ratcliffe is moving swiftly to ensure the CIA workforce is responsive to the administration’s national security priorities,” the CIA said in an emailed statement.

Donald Jr. has duck problem in Venice

Italian politicians on Tuesday asked authorities to take action against a hunting party including Donald Trump Jr. that may have killed a protected species of duck near Venice.

Andrea Zanoni of the Europa Verde party cited a video posted on the Field Ethos website for male adventurers. It shows Trump on a recent hunt in the wetlands in the Valle Pierimpie’ bordering the Venice Lagoon.

At one point, Trump is shown next to a dead duck that Zanoni identifies as a ruddy shelduck. The species is protected in Europe, and killing one is a criminal offense in Italy, Zanoni said.

The video picked up by Italian media does not indicate who killed the duck. It was not clear when the hunt took place, but Italian media said Trump was in Italy in December and a Christmas tree was seen.
