Satellite images show damage from Crimea blast

Satellite photos taken after a series of explosions on Tuesday at a Russian air base in Crimea appear to show at least three blast craters and at least eight wrecked warplanes, indicating a serious blow to the Russian military contradicting the Kremlin’s account. Russian authorities had previously denied that any aircraft had been destroyed.

A senior Ukrainian official has said the blasts were an attack carried out with the help of partisans but was not more specific. Military analysts have said that Ukraine does not have missiles that can reach the base from territory it controls, well over 100 miles away, and that Ukrainian jets would have been unlikely to penetrate that far into Russian-controlled airspace.

Witnesses reported multiple explosions at the Saki base. Officials said at least one person was killed and more than a dozen wounded. Sergei Aksyonov, the Kremlin-installed leader of Crimea, said that at least 62 apartment buildings and 20 commercial structures had been damaged. He declared a state of emergency and raised the terrorism threat level on the peninsula.

Background: Russia has heavily militarized Crimea since seizing it from Ukraine in 2014 and has used the peninsula as a vital jumping-off point for military operations since the broader invasion of Ukraine on Feb. 24. Even so, the attack on the air base suggests that Ukrainian forces are able to carry out guerrilla operations there.

Trump declines to answer questions under oath

Days after his home was searched by the F.B.I. in an unrelated investigation, Donald Trump invoked his constitutional right against self-incrimination while being questioned under oath by the New York State attorney general, Letitia James. The former president responded to every question posed by her investigators by repeating the phrase “same answer.”

Trump’s refusal to respond substantively could determine the course of the three-year civil investigation into whether the former president fraudulently inflated the value of his assets to secure loans and other benefits. He has long dismissed the inquiry but was compelled to sit for questioning under oath after multiple judges ruled against him this spring.

His only detailed comment, people with knowledge of the proceeding said, was an all-out attack on the attorney general and her inquiry, which he called a continuation of “the greatest witch hunt in the history of our country.” Reading from a prepared statement, he said that he was being targeted by lawyers, prosecutors and the news media.

Next steps: James is now left with a crucial decision: whether to sue Trump or seek a settlement that could extract a significant financial penalty. And while declining to answer questions might have offered the safest route for the former president, it could strengthen the attorney general’s hand in the weeks to come.

A U.N. agency’s oil and gas partners

A $1.9 million regional aid package unveiled by the United Nations Development Program on the edge of the Colombian Amazon is one example of how one of the world’s largest sustainable development organizations teams up with polluters, even those that at times work against the interests of the communities the agency is supposed to help.

A Times investigation found that U.N. partnerships with oil companies have led to the agency’s acting in the interests of those firms. In the program in the Amazon, the U.N. agency paired with GeoPark, a multinational petroleum company that holds contracts to drill near and potentially on the ancestral land of Indigenous Colombians like the Siona people.

These partnerships are part of a strategy that treats oil companies not as environmental villains but as major employers that can bring electricity to far-flung areas and economic growth to poor and middle-income nations. The development agency has used oil money to provide clean water and job training to areas that might otherwise be neglected.

Response: The development agency said it supports a clean energy transition and does not encourage drilling. But Achim Steiner, the agency head, said that its mission was to bring people out of poverty and often entailed working in countries built on fossil fuels. “We have to start where economies are today,” he said. “I don’t see a contradiction, but there is a tension.”

The black Issey Miyake turtleneck favored by Steve Jobs was not by any means the Japanese designer’s most interesting garment. It may even have been his most banal. But the turtleneck embodied Miyake’s founding principles and served as the door through which even those not particularly interested in fashion could enter the Miyake universe.

Memorializing those lost to Covid-19

Monuments have long commemorated the loss of life from calamitous events: wars, genocides, terrorist attacks.

But Covid-19 poses a unique challenge. Millions of people have died, but not in a singular event or in a single location. Now, as the death toll continues to rise, communities are building new monuments and expanding existing ones, trying to keep up with their mounting grief.

In Malaysia, photographs and biographies of victims are updated online. White ribbons flutter on a church fence in South Africa, and white flags dot the National Mall in Washington. In London, family members and friends have written the names of their dead on a wall alongside the River Thames, above.

“We really do need to remember, and we need to do it now,” said Erika Doss, a researcher at the University of Notre Dame. “Covid isn’t over. These are kind of odd memorials in that names are being added. They are kind of fluid. They are timeless.”
