The latest wave of attacks poses another challenge for Mali's military-led government, which has been battling multiple armed groups across the landlocked Sahel nation amid a prolonged insurgency.

Fresh violence erupted across parts of Mali on Saturday as explosions and heavy gunfire were reported in several towns following coordinated attacks by insurgents, underscoring the worsening security situation in the conflict-ridden West African nation.

A Tuareg-led insurgent group claimed responsibility for an attack on the northern town of Anefis, where Malian government troops and Russian paramilitary forces are stationed, while residents and local officials also reported gunfire and explosions in other northern and central parts of the country.

According to reports, the violence follows a series of high-profile rebel operations carried out in April, during which insurgents struck the airport in the capital, Bamako, reportedly killing the defence minister and capturing several army bases in northern Mali.
