Iran has been rocked by huge demonstrations since the September death in custody of Mahsa Amini, arrested for allegedly violating the country's dress code for women.  

Hundreds of people have been killed and thousands arrested in the unrest, described by authorities as "riots", prompting further protests in solidarity around the globe, including in Germany. 

Outside the Frankfurt consulate, a group of Iranian demonstrators had camped out in tents in the freezing winter weather to show support for the protest movement. 

Eight of them then decided to go on hunger strike, choosing only to drink water. 

"I am motivated by the murder of young people, women -- children -- and all people who are fighting peacefully for their freedom," Hossein Zandi, who had been on hunger strike for 13 days, told AFP. 

"My goal is that this consulate should be closed," added the 53-year-old.  

Ehsan Abbasy, who had stopped eating 24 days earlier, said he was starting to feel the impact.  

"My body has become very cold," he said, trying to keep warm in front of a heater.  

The protesters went on hunger strike for different periods of time, ranging from five to 24 days.  

They were supported by a network of volunteers from the local Iranian community and received daily medical check-ups to ensure their health was not in danger.  

However, their hunger strike was finally due to come to an end on Friday.  

One supporter, Fariba, said Iranians were rallying round to help each other "like a big family".  

"What has happened (in Iran) in the past three months has been unique during the past forty years," said the 55-year-old, who only gave one name.  

"We see real unity among Iranians."  

Several hundred Iranians also staged a demonstration outside the Frankfurt consulate Friday against the regime in Tehran, chanting and waving signs that read "Down with the oppressor".
