Surrounded by the frustrated chanting of her countrymen, a nine-year-old Syrian girl begins weeping as she recounts how happy she was to become a big sister.

But Jlanar Jaamoyr's baby brother brother lived only one day. The Aleppo hospital in which he was born was bombed barely 24 hours after he was born, she says.

"Shame on the world for being silent." - Protesters chanting outside the Russian consulate

"In Syria, why all the kids die? Why all the mothers need to cry?" she asks.

Jlanar came to Canada with her father and sister nine months ago. The family joined a throng of protesters outside the Russian consulate in Toronto night, decrying the lack of global intervention as Syrian President Bashar al-Assad and his military coalition of Russia, Iran and regional Shia militias took control of the war-torn city Tuesday night.

There have been reports of Syrian soldiers and their allies fatally shooting civilians in recaptured parts of Aleppo.

Protesters in Toronto carry photos of Assad and Russian President Vladimir Putin, both set against a backdrop of the ruined city lit by the orange of explosions.

"He's a children-killer," one woman yells, shaking a photo of the Syrian president. "Shame on the world for being silent.

"How many kids have been killed today?"

The ghosts of Aleppo

Jlanar wonders the same thing.

Sam Jisri holds her as she tells him about her brother, each wiping their eyes.

"They were very happy about the newborn baby; she still remembered him and she started crying," Jisri, the founder of Syrian Active Volunteer groups, says. "So she came here today to tell the world to stop this in any way they can."

The organizers say they had expected no more than 50 people to show up for the demonstration.

"But I think many people are so devastated about what happened in Aleppo and want to express their feelings," volunteer Rasha Elendari said.

Elendari, a Syrian herself, says she was happy to see so many Canadians at the rally. But she cannot understand how the country's leaders have not intervened in the recent fighting.

Ceasefire

Russia and Turkey negotiated a ceasefire between the rebels and the government military coalition on Tuesday, but other world powers were not involved in those discussions, Thomson Reuters reported.

"People are complaining about the refugee crisis, and now look," Elendari says. "The more bombing and the more shelling, the more refugees we will have. Why don't they [help] stop the shelling and stop the bombing? People would go back home.

"You think Syrians want to leave their country? They don't."
