Chad's army stopped and disarmed a Sudanese contingent of 320 soldiers who entered the West African country on Monday, Defence Minister Daoud Yaya Brahim said on Wednesday.
Brahim told a press conference that the confrontation between the Sudanese might create new waves of refugees and added that maintaining security would become difficult.
Chad's government closed its border with Sudan on Saturday and called for calm amid an apparent coup attempt in Khartoum by Sudan's main paramilitary group.
