Newspaper headlines: Aleppo boy, Brownlee brothers and Pennine tunnel
The picture of the boy in the ambulance in Aleppo and the Brownlee brothers' success in the Olympic triathlon dominate the front pages.
"The five-year-old boy sits caked in dust in the back of an ambulance, his feet dangling over the edge of the orange seat," says the Times. "Staring blankly ahead, eyes vacant with shock, he touches his head and, surprised to see blood, wipes his hand clean on the chair.
"Haunting video footage of Omran Daqneesh, the tiny survivor of a suspected Russian airstrike on the besieged Syrian city of Aleppo, has been seen around the world, providing a new, iconic face of a largely unseen tragedy.
"The image drew comparisons with that of Alan Kurdi, the Syrian boy whose body washed up on a Turkish beach, prompting a global outpouring of sympathy and influencing Angela Merkel's decision to open German borders to refugees."
The Times reports that Omran was wounded when the airstrike hit the Qaterji neighbourhood of Aleppo on Wednesday night. He was rescued with his mother, father and three siblings, aged one, six, and eleven. None had serious injuries but the building collapsed soon after their escape.
The Guardian says the picture of the injured child has become a new symbol of the horror in Syria.
"He brought his hand to his face, covered in a paste of blood and dust beneath a shock of grimy hair, and looked at the red stain on his fingers, a look of quiet surprise on his face," it says.
"Minutes earlier, the boy had been rescued from the rubble of his home in the rebel-held Syrian city of Aleppo after a government airstrike.
"His emergence from the debris in the neighbourhood of Qaterji was captured by local journalists who filmed the rescue and the ordeal of the boy and his family.
"The pictures were broadcast around the world yesterday as a symbol of the unrelenting, indiscriminate suffering of the country's civilians caught up in the civil war."
Stirred world's conscience
The Financial Times says the image was quickly seized on by social media as a damning symbol of the continued conflict in Syria.
"It echoed the picture of Alan Kurdi, the Syrian toddler who drowned off the coast of Turkey last September as his family attempted to escape to Europe," the FT continues.
The Telegraph says the photograph of the five-year-old has stirred the world's conscience to the daily plight of residents trapped in the city after five years of civil war.
Middle East correspondent Raf Sanchez writes: "With his face caked in dust and splattered with his own blood, the Syrian father began to dig through the rubble of what had been - until moments earlier - his family's home.
"He barely paused as he pulled his five-year-old son, Omran, from the wreckage caused by the Russian airstrike. Somewhere beneath the stones were four more of his children and his wife.
"He passed Omran to a man next to him, who passed the boy to another man, until the child had travelled through a human chain of volunteers to the backseat of an ambulance waiting on the street below.
"There the boy sat, his bare feet barely reaching the edge of the adult chair and his eyes glassy with shock, as he stared out through the ambulance doors and into the chaos beyond."
The Guardian comments that the "boy in the ambulance" stands for all children in war.
"Beneath the thick dark hair, his eyes are blank. It is the face of a child in trauma," it says.
"The image provokes such a visceral reaction that it feels uncomfortable, even exploitative."

Two people who are pictured on just about every front page are Great Britain's Alistair and Jonny Brownlee, who won gold and silver in the triathlon at Rio 2016.
"Meet the real Olympic family. They come from Yorkshire," says the Guardian.
It says the brothers "produced a moment of rare fraternal sporting beauty in the baking heat of Copacabana beachfront".
The Times says they swam, cycled and ran their way into Olympic history after becoming Britain's first siblings to take gold and silver in the same event.
The Telegraph says the brothers wrote their names into sporting legend with a unique brotherly one-two, then held each other and said: "We've done it!"
Brotherly love bound in gold and silver, declares the i.
The Sun says: "The brilliant Brownlee brothers blew away the opposition in one of the Games' most gruelling events yesterday."
The Mail states that they took gold and silver as Britain's medal tally "hit an incredible 55".
The Express describes their efforts as "superhuman" while the Star says there were emotional scenes at the finish line.
The Times reports that the world's longest road tunnel could be built under the Pennines.
It says the 20-mile, dual-bore tunnel - which would cost "well in excess" of £1bn - would cut 30 minutes off the driving time between Manchester and Sheffield and ease congestion on other roads.
"A government study admitted that a tunnel of this length could pose dangers for drivers, with fears over 'claustrophobia, disorientation and tiredness'," the Times adds.
"It suggested adopting tactics employed in other long road tunnels, such as the inclusion of mood lighting and changes to the shape of the walls to prevent motorists losing concentration."
The paper points out that the 15-mile Laerdal tunnel in Norway uses blue and yellow lighting to mimic a sunrise, while the 11-mile Zhongnanshan tunnel in China has artificial palm trees by the roadside and fake clouds above to relax motorists.
