A plea has gone out to Muslims across the North West not to travel to the war in Syria.
A charity is appealing to young muslims to focus on giving clothes, medicine, and their time, to a new centre in Manchester.
The message is that it is better to help here, than wage war there.
A centre aimed at taking aid to Syria has opened in Manchester today.
It is being supported by the police and city council, and aims at providing an alternative to travelling to Syria to help or fight.
It is believed that twin sisters Salma and Zahra Halane, from Manchester, left home last month in order to travel to the war-torn country.
When asked if he thought the Syria Relief centre could have helped stop the girls fleeing the country in order to help fight, Sir Peter Fahy said it could have.
He said: "Sometimes, some people in the Muslim community have felt we aren't bothered about Syria. But that's not the case. I think we're all bothered about Syria."
Today marks the launch of an initiative for volunteers to help humanitarian aid in Syria, to deter young men and women from going to fight in the war ravaged country.
The charity Syria Relief in Manchester is being backed by Greater Manchester Police and the council, with the opening of a new volunteering facility where humanitarian aid can be donated and packaged before being sent to Syria.
It comes after a number of young men and women have left their homes in the city to get involved in the troubled country.
A new centre's to open in Manchester later to take aid to Syria. People will be able to bring donations of food, clothes and blankets and to get involved in packing them onto containers.
It's being supported by the police, the city council and Syria Relief to provide an alternative to travelling to Syria to help.
GMP Chief Constable Sir Peter Fahy said: “We know there are many people in Greater Manchester and nationally who want to support the millions of people who are caught up in the Syrian conflict.
"Anyone who does travel there is putting themselves in considerable danger and that is why this volunteering facility is so valuable right here in Greater Manchester, giving people the opportunity to donate and assist with the humanitarian effort without putting themselves and others in danger."
Chairman of Syria Relief, Dr Basil Hatahet said: "While the news currently focuses on the brutality of the war and the emergence of fundamentalist groups in Syria, the ever-worsening humanitarian situation and human suffering continue.
“This joint initiative between Syria Relief, Manchester City Council and Great Manchester Police invites the citizens of Manchester to help alleviate the suffering by giving their time and efforts, as well as their financial and in-kind donation in a safe and practical way."
