#Trending: Global demonstrations of solidarity with Syria's Aleppo

In London, hundreds marched across through the city waving Syrian flags and sporting huge placards. They stopped outside Downing Street to protest over the "genocide" taking place in Aleppo, and held up traffic demanding the government take action to help Syrians. 

Red banners reading "Save Aleppo", "Hand-in-Hand with Aleppo" and "Enough with Assad" were carried across London in solidarity with civilians stranded in war-torn Syria. 

A note on the Facebook page for the event, hosted by the Syria Solidarity Campaign, read: "After the renewed assault on Aleppo since mid-November, the Assad regime and its allies are bombarding the city like there is no tomorrow.

"There is a Holocaust ongoing and we urgently need the international community to take action to save lives."

The demonstrations were echoed in Berlin, where hundreds of activists planned a march to Aleppo in protest of the killing of civilians inside the besieged city.

Holding banners saying "The children of Aleppo are calling you!", or "Aleppo is bleeding and the world is watching",  around 900 people braved plunging temperatures to gather in front to the Reichstag, the German parliament building.

Thousands gathered in the Bosnian capital this week, where protesters compared the siege in Aleppo to Serbian forces' one against Sarajevo in the 1990s, which claimed the lives of 10,000 people. 

Dozens of protesters gathered outside the Iranian embassy in Paris, where the local municipality turned off the lights of the iconic Eiffel Tower this week in solidarity with the people of Aleppo.

Hundreds of protestors also joined demonstrations in the cities of Lille, Strasbourg and Marseille.

The action was organised by the Humanitarian Relief Foundation [IHH] Turkish Muslim charity, which is playing a large role in the transport of aid for Aleppo and pressing for greater access.

Thousands of trapped civilians - and the last remaining opposition fighters - in Aleppo are awaiting to be evacuated to rebel-held Idlib, after Damascus halted the process.
