Two seperate attacks in Niger killed three policemen and a soldier, an official said, as the West African country heads to vote in a second round of presidential elections.
Attackers believed to be member of Al Qaeda in the Islamic Maghreb (AQIM) shot dead three policemen in a market in Dolbel near the Burkina Faso border, said Niger’s Interior Minister Hassimi Massaoudou.
"The attackers were repelled, and we are currently sweeping the area. We don't know the toll on the attackers side, they took their wounded and dead," he said.
In another attack near the Nigerian border on a military convoy a local military commander was killed and two others injured by four suicide bombers, the minister said.
However, no civillian casualities were reported from the attack.
Boko Haram militants were behind the second attack, according to the minister.
Niger will hold the second round of presidential elections on Sunday, which is expected to hand another term to current President Mahamadou Issoufou.
The opposition has already announced they will not recognise the results of the election, accusing the government of treating their candidate Hama Amadou - who is currently receiving medical treatment in Paris - unfairly.
Previously, AQIM claimed responsibility for an attack in which 16 people were killed in Ivory Coast’s capital Abidjan on March 13.
Attacks in recent months on luxury hotels in the capitals of neighbouring Mali and Burkina Faso have left dozens of people dead, leaving the West African nations scrambling to boost security in the face of a growing threat.
