Chad's government had on Saturday declared four Sudanese diplomats attached to Sudan's embassy in N'Djamena as "persona non grata" and ordered their exit from the country within 72 hours.

It made the decision after two Sudanese officials accused Chad's government of interfering in the ongoing conflict in Khartoum by supporting the paramilitary Rapid Support Forces (RSF).

"The recurrence of such statements by Sudanese authorities with regards to Chad and its government is simply not acceptable, hostile, and masks a hidden agenda," a spokesperson of Chad's government was quoted as saying in a statement by the Reuters news agency.
