A Limerick nun has become a London hero after removing an Islamist flag and taking on the might of terrorist group ISIS in her local community.

Sister Christine Frost, a 77-year-old member of the Faithful Companions of Jesus, has previously been awarded an MBE for her youth work in a deprived area of East London.

Now the Limerick native has become a cause celebre in England according to the Irish Independent newspaper.  

The paper reports that Sister Frost hit the headlines when she ordered the removal of a banner linked with the notorious Islamic State from the entrance of a housing estate in Poplar, East London.

She was concerned that the banner would lead to community tension in the area as similar flags have been flown in videos showing beheadings by the fanatical Islamist group.

She previously took down Islamist notices that branded Christmas ‘evil.’

She said then: “The more posters I saw, the more angry I got. If we said such things about Muslims, we’d all be hanging from lamp-posts.”

Sister Frost has denied she is a campaigner against Islam but says, on the contrary, that she has tried to highlight the social deprivation and sense of grievance that pushes Muslim youth in her area into the arms of extremists.

She insists that with care and attention she can persuade young Muslims to reject Jihad and embrace life in Britain and said her actions were never meant to set one faith against another.

She said: “We must find a way of bringing people together. We must create cohesion, or we will have a Bosnia/Serbia situation.”

Sister Christine also revealed that she knows what it is like to be an immigrant having moved from Limerick to London as a girl.

After leaving a convent school at 17 she qualified to study physiotherapy but chose to become a nun.

She added: “My parents wanted me to do the medical course, but I had a personal conviction.”

Now based at a community centre in the East End, she wants the nearby financial moguls in Canary Wharf to help the kids in her area.

She added: “I want the wealthy people who have millions and live in Canary Wharf to come over here and help the young people, get them into training. Make that an attractive alternative for them.”

She told the Irish Independent that many Muslims have a persecution complex, linked with Tony Blair’s invasion of Iraq and, more recently, Israeli attacks on Gaza.
