Words of condolence and sympathy from around the world have been offered by senior figures in sport and politics on Tuesday following the twin bomb attack that wreaked violent havoc at the Boston Marathon a day earlier.
The explosions in the crowded street killed at least three people and injured more than 140 in a bloody scene of shattered glass and severed limbs that raised alarms that extremists might have struck again in the US.
Japan's top government spokesperson, Yoshihide Suga said his country offers its "heartfelt sympathies to the victims and their families of this painful incident."
Taiwanese President, Ma Ying-jeou, also expressed his deepest condolences to the victims of the bombing.
He said his thoughts are with the families of those affected.
Australian Prime Minister Julia Gillard condemned the blasts and expressed Australia's condolences for those killed and injured in the explosions.
"The images we've seen have been truly shocking ones and our thoughts today are with those who have lost loved ones," she said.
Athletics Australia Chief Executive Officer Dallas O'Brien said he believes there were about 150 Australian runners in Boston.
He said the incident will not have an effect on the future of the marathon events.
Both Suga and Gillard said there were no initial indications that any Japanese or Australian nationals had been hurt in the blasts.
In the South Korean capital people expressed regret at the Boston bombing.
"This kind of incident should not have happened during a sports event. It is very sad," said housewife Kim Myung-hee.
It is not known what the motive was or who may have launched the attack.
Police have said no suspect is currently in custody.
Local media reported that a house was being searched in connection with the attack, although police did not confirm the reports.
The attack occurred at the heavily populated finish line of the centrepiece event of Boston's Patriots Day holiday.
It was a place certain to be filled with cameras held by professionals and amateurs alike.
As many as two unexploded bombs were also found near the end of the 26.2-mile (42-kilometre) course as part of what appeared to be a well-coordinated attack, but they were safely disarmed, according to a senior US intelligence official, who also spoke on condition of anonymity because of the continuing investigation.
Police said three people were killed with an eight-year-old boy was among the dead, according to a person who talked to a friend of the family and spoke on condition of anonymity.
Hospitals reported at least 144 injured, at least 17 of them critically.
The injuries ranged from cuts and bruises to amputations with many victims suffering lower leg injuries and shrapnel wounds.
Some suffered ruptured eardrums.
Some 23-thousand runners took part in the race, which attracts more than 500-thousand spectators and winds up in the heart of central Boston, near the landmark Prudential Centre and the Boston Public Library.
