President Mahmoud Ahmadinejad condoled and sympathized with the American people and the families of the children killed in the shooting spree incident of a school in Connecticut state, IRNA reported.
In his message, the Iranian president wished that one day all nations of the world would be living besides each other with peace and love.
'The horrific and bitter memory of the killings in a cinema in Colorado State and other frenzy-like murders in this country (US) had not been pacified that the recurrence of a much horrific incident intensified the concerns over this process and attracted the attention of the world's public opinion to the root-causes of such bitter incidents in the American society,' Ahmadinejad added.
'Today, all nations of the world, including the venerable American people in their evolutionary move towards the rule of ethics and spirituality as well as respecting the dignity of people need an atmosphere full of kindness and intimacy, and occurrence of such incidents cause deep concerns in everyone,' Ahmadinejad added.
On Friday, twenty schoolchildren were slaughtered by a heavily armed gunman who opened fire at a suburban elementary school in Connecticut on Friday, ultimately killing at least 27 people, including himself in one of the worst mass shootings in US history.
The 20-year-old gunman, identified by law enforcement sources as Adam Lanza, fired what witnesses described as dozens of shots in Sandy Hook Elementary School in Newtown, Connecticut, which serves children from ages 5 to 10. Lanza attended the school himself as a youngster, Reuters reported.
Authorities found 18 children and seven adults, including the gunman, dead at the school, and two children were pronounced dead later after being taken to a hospital.
Another adult was found dead at a related crime scene in Newtown, bringing the toll to 28, state police Lieutenant Paul Vance said. Police would not confirm or deny media reports that the person was Lanza's mother, Nancy.
