US indicates Rwanda hasn't assured safe passage of Congolese warlord at embassy

The top U.S. State Department official on Africa is indicating that Rwanda has not assured the safe passage of the internationally wanted Congolese warlord now holed up at the U.S. Embassy in Kigali.

Assistant Secretary of State Johnnie Carson told reporters via conference call Wednesday the U.S. hopes Rwanda will cooperate with the request by Bosco Ntaganda to travel to the International Criminal Court in the Netherlands to face charges.

Carson said it's important that Ntaganda's movement from the embassy to the airport "in no way be inhibited." Carson said the U.S. hopes ICC officials en route to Rwanda will be allowed into the country, another indication of U.S. concerns.

Ntaganda showed up at the U.S. Embassy in Rwanda's capital on Monday and asked to be transferred to the ICC.
