(Corrects to four not five taken to Khartoum including one U.N. staff member)
JUBA, April 28 (Reuters) - The United Nations mission in South Sudan (UNMISS) said on Saturday four people, including one U.N. staff member, had been taken to Khartoum.
Sudan said it had arrested a Norwegian, a Briton and a South African for illegally entering a disputed border area earlier on Saturday and accused them of helping the South Sudan army, a claim the South denied.
"Four people, including one U.N. staff member, were taken to Khartoum," Josephine Guerrero, a spokeswoman for the mission, said.
Guerrero declined to give any further details. (Reporting by Yara Bayoumy; Editing by Louise Ireland)
