Labour leader Jeremy Corbyn has also addressed worshippers at the Finsbury Park mosque in his north London constituency.
Speaking after Friday prayers he said:
?The message I?ve given them is that we?re absolutely shocked and appalled at the killings that have happened in New Zealand and the crazed gunman who has taken the lives of so many innocent people.
?What I just said to Friday Prayers is: an attack on a mosque, an attack on synagogue, an attack on a church, an attack on a temple is an attack on all of us.
So, those people who?ve died in New Zealand, that?s an attack on all of us. The only answer is one of respect for each other, support for each other, and solidarity.?
