After seizing power in August, the west African country's military government faces its first big security test.
The cat-and-mouse game across the West African nation's vast desert areas is the first big security test for Mauritania's new military government, which seized power in an Aug. 6 coup that overthrew the country's first democratically elected president.
The US has offered funds and training to Mauritania to help it fight the Al Qaeda-linked group, but cut such aid after the coup.
Agence France-Presse (AFP) quoted a Mauritanian lawmaker as saying the military was confident it would catch the attackers by blocking desert transit points and using air reconnaissance.
