A Kenyan court on Tuesday extended an order blocking a proposed US Ebola quarantine center for American citizens.

The controversial plan to build the 50-bed center at an air base in the central town of Nanyuki triggered protests this week. Hundreds of people clashed with security forces near the site, which they argue could expose them to Ebola.

"I can assure the people of Kenya that the agreement between the government of Kenya and the American government is for the good of our country and for the partnership," Kenyan President William Ruto said. "We are a responsible government. We know what we are doing. So people should relax."

Last week, a court temporarily suspended plans for the facility after an advocacy group filed a lawsuit alleging the center was being constructed in secret.

On Tuesday, Kenyan High Cout judge Patricia Nyaundi issued an order barring the Kenyan government from taking any further steps to begin operations at the facility before the case is resolved. She also ordered the government to disclose its agreement with Washington within seven days.
