For now, officials say they envision flying only unarmed surveillance drones from the base, though they have not ruled out conducting missile strikes at some point if the threat worsens.

If the base is approved, the most likely location for it would be in Niger, a largely desert nation on the eastern border of Mali, where French and Malian troops are now battling Qaeda-backed fighters who control the northern part of that country. The American military's Africa Command is also discussing options for the base with other countries in the region, including Burkina Faso, officials said.

The immediate impetus for a drone base in the region is to provide surveillance assistance to the French-led operation in Mali. "This is directly related to the Mali mission, but it could also give Africom a more enduring presence for ISR," one American military official said on Sunday, referring to intelligence, surveillance and reconnaissance.

A handful of unarmed Predator drones would carry out surveillance missions in the region and fill a desperate need for more detailed information on a range of regional threats, including militants in Mali and the unabated flow of fighters and weapons from Libya. American military commanders and intelligence analysts complain that such information has been sorely lacking.

The United States military has a very limited presence in Africa, with only one permanent base, in Djibouti, more than 3,000 miles from Mali. A new drone base in northwest Africa would join a constellation of small air bases in recent years on the continent, including in Ethiopia, for surveillance missions flown by drones or turboprop planes designed to look like civilian aircraft.

The Africa Command's planning still needs approval from the Pentagon and eventually from the White House, as well as from Niger officials. American military officials said that they were still working out some details, and that no final decision had been made. But in Niger on Monday, the two countries reached a status-of-forces agreement that provides legal protection to American troops in the country, including any who might deploy to a new drone base. The plan could face resistance from some in the White House who are wary of committing any additional American forces to a fight against a poorly understood web of extremist groups in North Africa.

If approved, the base could ultimately have as many as 300 United States military and contractor personnel, but it would probably begin with far fewer people than that, military officials said.

Some Africa specialists expressed concern that setting up a drone base in Niger or in a neighboring country, even if only to fly surveillance missions, could alienate local people who may associate the distinctive aircraft with deadly attacks in Pakistan, Yemen and Somalia.

Officials from Niger did not respond to e-mails over the weekend about the plan, but its president, Mahamadou Issoufou, has expressed a willingness to establish what he called in a recent interview "a long-term strategic relationship with the U.S."

"What's happening in northern Mali is a big concern for us because what's happening in northern Mali can also happen to us," Mr. Issoufou said in an interview at the presidential palace in Niamey, Niger's capital, the day before French troops swept into Mali on Jan. 11 to blunt the Islamist advance.

Gen. Carter F. Ham, the head of the Africa Command, who visited Niger this month to discuss expanding the country's security cooperation with the United States, declined to comment on the proposed drone base, saying in an e-mail that the subject was "too operational for me to confirm or deny."

Discussions about the drone base come at a time when the French operation in Mali and a militant attack on a remote gas field in the Algerian desert that left at least 37 hostages, including 3 Americans, dead have thrown a spotlight on Al Qaeda's franchise in the region, Al Qaeda in the Islamic Maghreb, and forced Western governments and their allies in the region to accelerate efforts to combat it.

Senator Dianne Feinstein, a California Democrat who heads the Intelligence Committee, said on the CBS program "Face the Nation" on Sunday that in the wake of Osama bin Laden's death and the turmoil of the Arab Spring, there was "an effort to establish a beachhead for terrorism, a joining together of terrorist organizations."
