Vietnam PM: US 'committed barbarous crimes' during war
Vietnam's prime minister has spoken of "countless barbarous crimes" committed by the US during the Vietnam War.
Nguyen Tan Dung was speaking at an event in Ho Chi Minh City to mark the 40th anniversary of the end of the war.
On 30 April 1975 the city - which was then called Saigon and was the capital of South Vietnam - was captured by communist troops from the North.
Three million Vietnamese, and 58,000 US soldiers died in the war. But the US and Vietnam now have diplomatic ties.
Speaking in front of the former Presidential Palace Mr Dung said: "[The US] committed countless barbarous crimes, caused immeasurable losses and pain to our people and country".
"Our homeland had to undergo extremely serious challenges."
Some in Vietnam are still suffering from deformities and the lasting effects of the dioxin Agent Orange, sprayed by the US Air Force into the thick jungle used as cover by northern guerrilla forces.
Soldiers and veterans
Eventually the US-backed South was defeated and the North's tanks smashed through the gates of the palace in Ho Chi Minh City ending the conflict. The reunification process was completed the next year.
Vietnam's relationship with the US has changed significantly since then. They now have diplomatic ties and are trade partners.
On Thursday, regiments of soldiers and war veterans took park in an elaborate commemorative parade to pay tribute to those who fought and died in the long conflict.

When I was 16 months old my mother went to war. Duong Thi Xuan Quy became North Vietnam's first female war correspondent, but - and it's a familiar story in a country where three million died - she never came home.
We are still searching for her remains.

The North's victory reunited Vietnam under the communist government.
The war was very divisive in the US as well, as it was the first to be extensively covered by US TV. It was also the first to be lost by a modern global superpower.
Hundreds of thousands of people left the South in the years that followed the war, some risking their lives on dangerous boat journeys. Most of them ended up resettling in the US, UK, France and other countries.
