June 2 (UPI) -- A plan for a quarantine site in Kenya for Americans exposed to Ebola is on hold for at least another three weeks as a court ruled to pause it and Kenyans have taken to the streets in protest.

Lady Justice Patricia Nyaundi extended a block on creating the center at the Laikipia Air Base near Nanyuki, Kenya, until June 23. The plan was stopped last week after the Katiba Institute, a Kenyan group that defends the country's constitution, sued.

The outbreak in the Democratic Republic of Congo has afflicted about 1,000 people, with about 200 suspected deaths. It hasn't spread to Kenya, but some Kenyans fear it could.

Trump has said that no Americans would be allowed to come home for treatment, while several of them are being monitored or getting treatment in Europe after exposure in Congo or Uganda.
