By nightfall, demonstrators were still clashing with police, who fired tear gas and bird shot, according to activist Abdullah el-Nikeety.
“All of Mansoura will not allow this death to be in vain,” he said. “I am seeing people who are protesting for the first time.”
The ministry said 12 policemen were wounded, nine by bird shot. Police arrested 28 people.
Abdel-Rahman Saad, a law student in Mansoura, likened Saturday’s violence to what happened on Jan. 28, 2011, the bloodiest day of the uprising against President Hosni Mubarak that led to his ouster. The office of the opposition “Tayar al-Shaabi” was turned into a field hospital to treat the wounded, he said.
Saad was among around 100 protesters who had been demonstrating on Monday along a main road in Mansoura, convincing some government employees on their way home from work to join the strike. He and others there said pro-Brotherhood residents assaulted their sit-in, and that both sides threw rocks at one another.
Police moved in to try to stop the fight that day, but clashes have continued between protesters and security forces since.
Activists uploaded videos of the violence online. One video purported to show an armored police vehicle rushing protesters at high speed on Thursday. Another video showed a protester from the overnight clashes Saturday with what appeared to be a crushed skull. The videos could not be independently verified.
Tayar al-Shaabi released a statement, saying police violence is unjustified and accused security forces of deliberately running over the protester who died. It accused Morsi and his Brotherhood backers of tyranny and said the violence in Mansoura and other cities is evidence of “people’s rejection of the current regime.”
Elsewhere in Egypt, a police car in the restive Suez Canal city of Port Said hit five protesters along a main road and sped off, according to an AP reporter at the scene. The protesters were blocking traffic during an anti-government march.
The reporter said that when the protesters refused to allow a police car passage, the driver fired warning shots into the air and rammed into the crowd, hitting five people. The protesters, who are angry with the police, then torched a number of vehicles at a nearby police station, the AP reporter said.
A police official said demonstrators first threw stones at the police vehicle before the driver hit protesters. Several hundred protesters then threw firebombs at the nearby police station, causing part of it to catch fire, the official said, speaking anonymously because he was not authorized to speak to media.
Health official Helmy el-Afani said those hit by the car were admitted to a nearby hospital with broken bones, including one man who had a broken pelvis.
Schools have been closed for a month in Port Said following deadly clashes there late last month that killed around 40 people. The violence erupted after protesters tried to storm the city’s prison in January to free 21 defendants sentenced to death for their roles in a deadly soccer riot.
It was unclear if schools would resume classes on Sunday as planned.
ElBaradei’s Dustor Party said the violence was reminiscent of police assaults on protesters during the anti-Mubarak uprising. It condemned what it said was “an excessive use of force” by police and Brotherhood loyalists.
