A judge Friday paused the removal of eight migrants currently detained in Djibouti, setting off a race against time before they were scheduled to be sent to South Sudan.

Murphy’s May 21 ruling found that the government violated his April 18 order by attempting to deport eight men to South Sudan. The U.S. has evacuated all non-emergency personnel from South Sudan, and the State Department advises against travel there due to “crime, kidnapping, and armed conflict.”

The Supreme Court on Thursday cleared the way for the the Trump administration to deport to South Sudan a group of migrants that have been held for weeks on a military base in Djibouti.
