Ethiopian volcano disrupts flights

From the BBC World Service: The world’s largest cryptocurrency exchange, Binance, and its founder, Changpeng Zhao, are being sued by victims and family members of victims in the October 2023 attack in Israel. They're accusing Binance of knowingly enabling terrorist groups like Hamas to move more than $1 billion through its platform. Also: a slowdown at Serbia's Russian-owned oil refinery, growing risks to European undersea cables, and rerouted flights after an Ethiopian volcano eruption.
