The driver of a double-decker bus which crashed into a Sainsbury's killing two people is "devastated", his family said.
In a statement they expressed their "deepest and most sincere condolences to those involved".
They said of the 77-year-old: "Being a grandfather himself, he is devastated to the core by what has happened. We feel deeply for everyone affected by this terrible tragedy.
"He is a very quiet man, and a caring and devoted person. He has strong ties with the local community and has spent most of his life helping and thinking of others. This is just beyond anyone’s imagination.
"We would only ask that the privacy of the families is respected at this tragic time and the police are given space to complete their investigation."
The United States military has expressed "deepest condolences" to the civilians killed in an airstrike on a hospital in Kunduz, Afghanistan.
Pentagon official General John Campbell says that Afghan forces said they were taking fire from enemy positions and asked for air support.
General Campbell said the Taliban for "fighting within the city" that put civilians in harm's way, and US advice and air support would still be available for Afghan forces despite the tragedy.
"We have now learned that on 3rd October Afghan forces advised that they were taking fire from enemy positions and asked for air support from U.S. forces," Campbell said. "An air strike was then called to eliminate the Taliban threat and several civilians were accidentally struck."
He did not specify if the air strike had struck the Medecins Sans Frontieres hospital.
The deadly air strike on Saturday killed 22 people when it hit the medical facility.
Investigations by Nato and Afghan forces will be carried out, Campbell said.
Police say they have "no idea" who killed an on-duty PC trying to stop a burglar getting away in a stolen pick-up truck.
Merseyside Chief Constable Sir Jon Murphy said the only evidence they have is the truck, which was later found abandoned.
"We have got no idea who has done this," he said as he appealed for information on PC David Phillips' death, which they are treating as murder.
Anyone with information is asked to call Matrix serious organised crime unit on 0800 230 0600 or Crimestoppers on 0800 555 111.
Two people killed in a bus crash in Coventry at the weekend have been named by their families.
Rowan Fitzgerald, 7, of Leamington Spa and Dora Hancox, in her 70s, of Nuneaton, both died when a double decker bus collided with a supermarket.
Rowan’s cousin, an eight-year-old girl, was also injured and she remains in a stable condition in hospital.
The children were travelling with their grandparents on the bus when the accident happened.
Five other people were injured in the crash.
Inspector Paul Bennett, from West Midlands Police, said:
The bus driver, a 77-year-old man, has not been arrested but "continues to help investigators", police say.
The chair of Merseyside Police Federation said the force has lost a "respected and truly exceptional officer" after the death of PC David Phillips.
Peter Singleton said it was a "desolate" day when any officer is killed but in PC Phillips' case "possibly more so".
He told a press conference: "His young children have been robbed of a father, his wife Jen deprived of a husband and his parents their son.
"He colleagues and friends have lost a truly exceptional officer. He was one of the best and will always be missed."
PC Phillips was killed by a stolen car which was trying to flee police following a burglary.
George Osborne thanked David Cameron for his support in a conference speech viewed by many as a pitch to be his successor.
The Chancellor gave a special thank you to the Prime Minister during his address in Manchester, thanking him for his support when some had doubted his abilities during the coalition government's five-year term.
"Let's face it, there were moments when lots of people had doubts about whether our plans would work - moments, as I was well aware, that people had doubts about me."
He added that "my friend" Mr Cameron had supported him both privately and publicly during that period.
Merseyside police and crime commissioner said "today is a day of mourning for the entire police family" as she spoke about the death of PC David Phillips.
Addressing a press conference Jane Kennedy's voice broke with emotion as she said: "It's a dark day when you lose one of our own.
"And it's a painful reminder of the risks police officers face to keep us all safe.
"I know I speak for people across Merseyside when I say my thoughts and deepest sympathies are with PC Phillips family, his friends and their colleagues during this time."
