– The death toll in the protests sweeping Iran is now at least 20—and it could end up a lot higher under a recommendation from the head of Tehran's Revolutionary Court. According to Iran's semi-official Tasnim News Agency, Mousa Ghazanfarabadi said Tuesday that some of the hundreds of protesters arrested around the country could face the death penalty for "waging war against God," the AP reports. At least 450 people are believed to have been arrested in Tehran alone since Saturday. President Hassan Rouhani says he can understand public anger at the economy, but lawbreaking will not be tolerated. In other developments: Support from Trump. President Trump has tweeted in support of the protesters, and administration officials say they're urging other nations to support Iranians' right to protest. "We are encouraging all nations around the world to publicly condemn the government violence and to support the legitimate, basic rights of those protesting," Brian Hook, the State Department's director of policy planning, tells the Wall Street Journal.
