UN Secretary-General Kofi Annan voiced deep regret on Friday over the clashes in Cairo between Sudanese refugees and Egyptian police, saying the deaths of a number of refugees were unjustified.
"The secretary-general was deeply saddened to learn of the violent deaths of a number of Sudanese migrants in Cairo today as a result of clashes with police," said a statement issued by a UN spokesman.
"Their deaths are a terrible tragedy that cannot be justified," it added.
At least 10 refugees were killed in clashes when Egyptian police tried to clear a Sudanese refugee protest camp at a small park in Cairo before dawn on Friday local time.
"The secretary-general extends his heartfelt sympathies to the families of all of those who were killed and injured," the statement said.
"He expresses his profound regret that this situation was not resolved peacefully and through dialogue, as the UN High Commissioner for Refugees had strongly urged."
