CAIRO — Standing on her balcony in the Iranian capital, Tehran, the teacher shouted out into the darkness, ''Death to the dictator!'' and ''Death to the murderer, Khamenei!'' on a recent night, joining the slogans coming from windows and rooftops around her relatively affluent neighborhood.
A few voices in the darkness responded with slogans in support of Iran's 47-year-old Islamic Republic.
''Shut up! Choke on it!'' her neighbors shouted back, drowning out the pro-government voices, the teacher recounted to The Associated Press, speaking on condition of anonymity for her safety.
Iranians across the country are still reeling with shock, grief and fear after massive nationwide protests were crushed by the deadliest crackdown ever seen under the rule of the 86-year-old Supreme Leader Ali Khamenei. Thousands were killed and tens of thousands are believed to have been arrested.
But a vein of defiance persists. A seething anger at Iran's rulers is evident in videos shared on social media and in conversations with protesters. At the same time, three protesters reached by the AP also expressed futility over what can be done after hundreds of thousands braved taking to the streets only to be met with overwhelming violence. The protesters all spoke on condition of anonymity, fearing retribution or arrest.
Adding to the uncertainty is the United States' threat to strike Iran. The U.S. has positioned warships and fighter jets nearby even as it holds negotiations with Iran over its nuclear program.
The defiance appears in the shouting of slogans from windows and rooftops at night, a ritual displayed in past waves of protests.
It is also evident at memorial gatherings for those killed 40 days earlier. Such commemorations -- known as the ''chehelom,'' Persian for ''the 40th'' – are traditionally held by families for anyone who has died. But in times of unrest, chehelom can have a political dimension.
