NAIROBI, Kenya (AP) — A court in Kenya on Friday suspended a U.S. plan to establish a quarantine facility for Americans exposed to a rare type of Ebola virus spreading in northeastern Congo, following a backlash.

The Congolese government has confirmed more than 1,000 suspected cases, with at least 220 deaths, since it declared an outbreak on May 15.

U.S. administration officials said on Thursday that the U.S. was planning to send Americans who are exposed to Ebola while abroad to a new facility in Kenya instead of flying them home. The officials spoke on condition of anonymity to share the administration’s plans. They said the facility would be at Laikipia Air Base and would be operational with 50 quarantine beds by Friday.

The Kenyan government said it was in discussions with the U.S. on support for Ebola preparedness, but declined to address whether the country would establish a treatment facility for Americans. The U.S. government intends to commit $13.5 million toward Kenya’s Ebola preparedness efforts, Secretary of State Marco Rubio said in a statement.

The High Court in Nairobi on Friday put a stop to any deal on the facility until petitions against it are heard on Tuesday.

An group formed to defend Kenya’s Constitution, Katiba Institute, and the Kenya Law Society separately challenged any presence of Ebola-related facilities. The Kenya Law Society asked the court to nullify any agreements signed between the U.S. and Kenya on the project, citing public health risks and a lack of public participation
