The neo-fascist party’s leaders were convicted of running a criminal organization, and some of its members were found guilty of acts of violence.

ATHENS — An Athens court sentenced the leadership of Greece’s Golden Dawn party to 13 years in prison on Wednesday, a week after declaring the neo-fascist party a criminal organization in a landmark verdict that wrapped up one of the most important political trials in the country’s modern history.

Last week, the court convicted the party leaders of crimes related to a campaign of attacks against migrants and leftist critics in 2012 and 2013. At the end of a trial that lasted more than five years, the party was tied to a string of attacks, including the fatal stabbing in 2013 of a left-wing rapper, Pavlos Fyssas.

Giorgos Roupakias, a party member convicted of murdering Mr. Fyssas, received the harshest sentence, life plus 10 years. The court could still suspend some of the sentences.

The convictions were widely seen in Greece as a final blow to Golden Dawn, which failed to re-enter Parliament in general elections last year as the trial gradually eroded its popularity. And the outcome has already spurred political upheaval.

The Supreme Court on Friday put off action on a request from the Food and Drug Administration to reinstate a federal requirement that a pill used to induce abortion in the early stages of pregnancy be picked up in person from a health care provider. A federal district court in Maryland had suspended the requirement in July, concluding that requiring in-person visits during the COVID-19 pandemic violates the Constitution. The FDA asked the justices in August to block the district court’s order while it appealed, but the justices told the government on Thursday night to go back to the district court to ask for a less sweeping order there.

The regulations at the center of Friday’s order govern the dispensation of Mifeprex, the brand name for mifepristone, which the FDA has approved to end pregnancies through the first 10 weeks. The FDA’s regulations require patients to receive the drug from a health care provider in a medical setting, after signing a form acknowledging risks associated with the drug. After picking up the drug from a hospital or clinic, patients can take the pill at home, but the regulations do not permit patients to receive the pill by mail.
