Among Iranian communities from London to Los Angeles, few tears are being shed over the death of President Ebrahim Raisi, killed in a weekend helicopter crash.

But there are not always loud cheers, either.

While some hope the demise of a powerful figure in Iran’s authoritarian Islamic government may bring change, others fear it could result in more repression.

“It’s a better world without him,” said Maryam Namazie, a U.K.-based women’s rights campaigner. “He is one of the pillars of the Islamic regime of Iran. He has been there since its inception.”

But, she added: “Raisi, however much of a pillar he was, is expendable. There are many others to take his place.”

Inside Iran, authorities are keeping a tight lid on reaction to the crash that killed Raisi, Foreign Minister Hossein Amirabdollahian and six others. The government declared five days of mourning, encouraging people into the streets in displays of public grief and support. Prosecutors have warned Iranians against any public celebrations, and a heavy security force presence has been on the streets of Tehran.
