Some sources put the number at more than six but Police authorities are yet to confirm the number to the Ghana News Agency.
Sources told the Ghana News Agency that the clash started after the alleged killing of an old man and his son at Natinga on Saturday.
According to them, the old man was shot dead at his home, while his son died later on Sunday.
Some houses have also been burnt.
The security forces stationed in the area have, however, restored calm there.
The protracted conflict has to do with disagreement over the performance of the funeral of a chief who died more than 42 years ago.
This would pave the way for the enskinment of another chief.
Some residents complain that Bawku has no an Overlord.
Since the re-start of the conflict in November 2021, many lives have been lost while properties including houses, were destroyed.
The situation prompted the government through the Ministry of the Interior to impose a curfew on the movement of people in the area.
But in October 2022, REGSEC temporally lifted the ban on the operations of tricycles after persistent appeals from public sector workers over lack of means of transport to their workplaces.
In September, 2022, a high-powered government delegation, including Mr Ambrose Dery, Minister of the Interior, Mr Dominic Nitiwul, the Minister of Defence and the Inspector General of Police, Dr George Akuffo-Dampare, and some staff from the two Ministries, also visited the area to engage the factions in the conflict to give peace a chance.
Meanwhile, the Government, through the Ministry of Chieftaincy and Religious Affairs, noted that the Chieftaincy disagreement was settled by the Supreme Court in 2003 and urged all parties to respect the ruling.
