Ukrainian drone strikes have raised anxiety across Moscow ahead of this year’s May 9 parade on Red Square, which Vladimir Putin will watch with other leaders.

The volley came just days before a planned parade in the capital to mark the 80th anniversary of the end of World War II in Europe.

All four international airports around Moscow temporarily suspended flights as Russia said its forces intercepted more than 100 Ukrainian drones.

Explosions and fires rocked Sudan’s main port city and wartime capital Port Sudan on Tuesday, a witness said, part of a days-long drone assault that has torched the country’s biggest fuel depot, damaging the most important gateway for foreign aid.

Sudan's army said its anti-aircraft systems intercepted drones on Wednesday targeting a naval base in the wartime capital Port Sudan. Explosions were heard in the city, though it was not immediately clear whether they were near the Flamingo base.
