The authorities in Uzbekistan have taken a group of foreign diplomats and journalists to the eastern town of Andijan, where many people were killed when troops opened fire on protestors last week.
However, the two-hour visit took place under strict government control and the group was not shown the scene of the killings or allowed to speak to locals.
One of the visitors was the British ambassador to Uzbekistan, David Moran, who said not all questions had been answered.
A news blackout had been in force after correspondents were asked to leave on Saturday.
The Uzbek government says 169 people died in the shootings and blames Islamic militants for provoking the violence. Witnesses’ reports suggest up to 500 people had been killed.
The American Secretary of State, Condoleezza Rice, has called on the Uzbek government to open the country's political system to reform.
Meanwhile, the United Nations' top human rights official, Louise Arbour, has called for an investigation into the reported killings last Friday.
Ahern calls for peaceful resolution
The Minister for Foreign Affairs, Dermot Ahern, has called for the current unrest in Uzbekistan to be resolved without further bloodshed.
Mr Ahern said that credible reports that many of the killings in Andijan last Friday were the result of firing by military forces on unarmed civilians were extremely disturbing.
He called on the Uzbek authorities to exercise the utmost restraint in dealing with any further protests. He also called on all opposition groups to refrain from violence.
