African leaders are calling on Western countries to intervene in Libya to stem a flow of arms to militant groups in the Sahel region.

Libya is mired in the worst fighting since dictator Moammar Gadhafi was overthrown in 2011, leaving the country with two rival governments. In the chaos, arms have flowed from Libya into Africa's Sahel region, home to several militant groups.

France is moving troops toward the Libyan border partially to track such arm shipments.

But Chadian President Idriss Deby and others said Tuesday more needs to be done and the region's security depends on it. He told a security summit in Dakar, Senegal: "The solution to the crisis that is shaking this country is not in African hands, but in the hands of the West, notably NATO."
