Mr Boutros-Ghali said South Africa's President, Nelson Mandela, and some European states, including Italy, had also agreed in principle to commit troops to a humanitarian force.
"We are in contact with Canada, Italy, France, Spain and we hope also to have logistical support from the United States." The size of the force had not been decided but Mr Boutros-Ghali said: "People are talking of between 10,000 and 12,000."
Mr Boutros-Ghali said he was confident a Canadian-led force, with African participation, would prove acceptable to Rwanda's Tutsi-led government, which has refused to agree to leadership from Paris. the government says that French troops sent in 1994 to help end the genocide protected Hutus who were blamed for the slaughter.

Britain has said that it will take a preliminary decision in the next "couple of days" on whether to contribute personnel to a proposed humanitarian force in Zaire.

Spain's Foreign Minister, Abel Matutes, said that the UN might give a green light within 48 hours to the deployment of a multinational force in Zaire. Spain was prepared to send 300 soldiers to secure humanitarian corridors and would consider whether to send more later.
