Nicola Sturgeon has called for tolerance and peace on a visit to the mosque of murdered shopkeeper Asad Shah.

The First Minister met with members of the Ahmadiyyah community to launch their "true Islam" campaign which aims to raise awareness and understanding of their religion, whose members still face persecution in many parts of the world.

Mr Shah was a member of the Ahmadiyya Mosque in the city, and his killer Tanveer Ahmed claimed the popular shopkeeper had "disrespected the Prophet Muhammad".

After the visit to the mosque in Glasgow, Ms Sturgeon spoke at a special Peace Symposium taking place at Glasgow University.

The First Minister said: "Diversity is one of our great strengths as a country and we've got to work to make sure that, that tolerance and understanding is protected and nourished.

"The Ahmadiyya community in Glasgow has suffered great tragedy through the horrific murder of Asad Shah, which has brought to light many of the issues of prejudice and persecution that this community faces not just in Scotland, but around the world.

"And therefore it's an opportunity for us to underline the importance of peace and tolerance and respect in our diverse country.

The Shah family had moved to Scotland from Pakistan in the 1990s to escape persecution as a result of their religious beliefs.

Ahmed, a father-of-three from Bradford who did not know Mr Shah, claimed to have been offended by clips the shopkeeper had posted online which he said "disrespected the Prophet Muhammad".

On the day he carried out the murder, he watched a clip featuring Mr Shah on his mobile phone as he travelled to Glasgow.

Ahmed was heard to say in a phone message: "Listen to this guy, something needs to be done, it needs nipped in the bud."

When he arrived at the shop, Ahmed said he warned the shopkeeper he was there to kill him and asked him to stop claiming to be a prophet.

Mr Shah's brother and a shop assistant tried to fend him off as he launched his attack on the popular businessman, who was described by locals as a "pillar of the community".

Ahmed was given a life sentence at the High Court in Glasgow after admitting the murder in Glasgow's Shawlands area on March 24.
