According to the BBC, to date at least 348 Iranian protesters have been killed and nearly 16,000 arrested in women-led protests that erupted three months ago after the death Mahsa Amini, a 22-year-old woman who died in custody after being detained by morality police for allegedly breaking the strict rules on the wearing of hijabs.

One way the regime has responded to these antigovernment protests is to block access to the internet, independent news sites and social media and communication platforms. To talk more about how these tactics are being applied in Iran and around the world, and what policymakers in democratic countries can do to help dissidents on the ground, I spoke to two experts on digital and human rights:

• Yasmin Green, CEO of Jigsaw and author of a recent piece in Wired on Iran's internet blackouts
• Kian Vesteinsson, Senior Research Analyst for Technology and Democracy at Freedom House, one of the authors of the 12th annual Internet Freedom Report
