Dubai: Iranian social media posts urged citizens to take to the streets for a fifth day on Wednesday, after public anger erupted following the belated admission by the authorities that they had shot down a passenger plane in error last week.
Protesters, with students at the forefront, have staged daily rallies in Tehran and other cities since Saturday, when the authorities admitted their role in bringing down a Ukrainian plane last week, killing all 176 aboard, after days of denials.
The plane was downed by air defences on January 8 when the armed forces were on high alert for US reprisals following tit-for-tat military strikes, the latest escalation in a crisis that has rumbled on for years over Iran's nuclear programme.
Iran's president called the plane disaster an "unforgivable error", the military has issued profuse apologies and the judiciary said it had arrested some of those accused of having a role in the crash, in the effort to quell public outrage.
Some protests have been met with a violent crackdown. Videos on social media have showed people being beaten by riot police and shocked with electric batons. They also recorded gunfire and blood on the ground. Most protests flared at night.
"We're coming to the streets," one posting circulating on social media said on Wednesday, urging people to join nationwide demonstrations against a "thieving and corrupt government".
Wednesday marks a week since the crash. Tuesday's protests appeared smaller, with postings showing peaceful demonstrations, mainly on university campuses.
Thousands of protesters have been shown in videos gathering in the past four days in cities across Iran. Many have been outside universities, while Tehran's central Azadi Square has been a focus. But the full scale of protests and unrest is difficult to determine due restrictions on independent reporting.
State-affiliated media have reported protests taking place, but have given limited details.
