Messages of condolence have been pouring into the Evening Times website, Twitter account and Facebook page from around the world.

Many echo the shock felt across the city, many others express great sadness.

Here are just a few.

l Francine Sidler said: "My sincere condolences to all the families of the victims in the Clutha Bar crash."

l John Watcher, from Glasgow, said: "The real stars of this tragic event were the citizens of Glasgow, many of whom re-entered the Clutha Vaults to form a human-chain to evacuate, and remove to safety, their fellow citizens. Well done to you all."

l Glasgow expat Tom McCoist, who now lives in the United States said: "I spent many a happy night in the Clutha, my heart goes out to everyone concerned.

"Glaswegians have a way of handling tragedies. It looks like everyone pulled together once again. I hope everyone concerned finds some resolve and closure."

l Jane Guthrie-Tate, of Glasgow, wrote: "My heart goes out for the police lost and the pilot.

"The spirit of Glasgow has to be applauded and admired for running INTO a building in trouble not running away from it. I applaud all Glaswegians and others on the scene that did not turn a blind eye and helped. Bless you."

l Fiona Dow said: "Just awful news."

l Lubo Dobrev said: "The bravery of the Glaswegians has been recognised globally.

l Andrew Morrison praised the Scots who rushed back into the scene rather than away: "Especially brave considering the risk of explosion if fuel was still onboard the helicopter."

l Anne Marie said, with regards to missing Mark O'prey, whose phone was ringing from within the rubble: "That is the saddest thing I've ever read. The hope and the terror of those lines is unimaginable."

l Martin Anthony continued with that thought, commenting: "What a horrible thing for anyone to go through."

l As friends and family of Mark O'prey encouraged the emergency services to work faster to find his body, Colin Armstrong put it simply, calling the situation: "Heartbreaking"

l Other contributors praised the emergency serviced for their work. Ruth Barr posted: "It must be hard but the emergency services are doing their best to get the answers as quick and as safe possible."

l And Celtic fan Louise Sharp praised her Old Firm rivals for holding a minute's silence before their Scottish Cup game against Falkirk on Saturday. Louise posted: "I'm a Celtic fan and I would like to think that all football clubs are doing that."

Elsewhere on the boards, messages of condolence came in from expat Scots in Canada, South Africa, Australia and New Zealand.
