BAMAKO, Mali — French special forces inched closer to an Al Qaeda-held town, fighting erupted in another center, and army troops raced to protect a third, as the Islamist extremists controlling northern Mali ceded no ground Thursday, digging into the areas they already occupy and sending out scouts to widen their reach.
Banamba, a town 90 miles from the capital, Bamako, was put on alert overnight and a contingent of roughly 100 Malian soldiers sped there on Thursday after a reported sighting of jihadists in the vicinity, the closest the extremists have come to the seat of government of this West African country, officials said.
France has encountered fierce resistance from the extremist groups, whose tentacles extend not only over a territory the size of Afghanistan in Mali, but also another 600 miles to the east in Algeria, where fighters belonging to a cell in Mali stormed a BP-operated plant and took dozens of foreigners hostages, including Americans in retaliation for the French-led military operation in Mali. They demanded the immediate end of the hostilities in Mali, with one commander, Oumar Ould Hamaha, saying that they are now ‘‘globalizing the conflict’’ in revenge for the military assault on Malian soil.
The first Malian troops arrived in Banamba late Wednesday, with a second group coming on Thursday. The small town northeast of Bamako is connected by a secondary road to the garrison town of Diabaly, which was taken by Islamist extremists earlier this week, and has been the scene of intense fighting with French military, as French troops continued to move closer, following another night of airstrikes.
To the south of Banamba, flanked by emerald rice fields and crisscrossed by irrigation canals, is the first government-held city, Niono. And another 75 miles south is Segou, one of the largest towns in Mali, and the administrative capital of its central region. As refugees from Diabaly continued to flee south, authorities announced a state of alert including the closure of the largest road after sundown, fearing that the Al Qaeda-linked fighters would try to infiltrate the towns in the south.
A city official in Banamba who insisted on anonymity because he is not authorized to speak to the press said they had received reports that a rebel convoy had left Diabaly on the road headed to Banamba.
‘‘We don’t have a [military] base here, we have no defenses. So the military has come to secure the town,’’ he said. ‘‘No jihadists have entered our town. But there are reports that a column [of rebel vehicles] was seen heading toward us from Diabaly.’’
France has stepped up its involvement every day, after launching the first air raids last Friday in an effort to stop the rebels’ advance. On Thursday, it increased its troop strength to 1,400, said French Defense Minister Jean-Yves Le Drian.
‘‘The actions of French forces, be it air forces or ground forces, are ongoing,’’ said Le Drian in Paris.
After a meeting in Brussels of European Union foreign ministers,Mali’s foreign minister, Tieman Hubert Coulibaly, said it was necessary to mobilize ‘‘the entire international community’’ to help Mali and the region.
‘‘What is happening in Mali is a global threat,’’ Coulibaly said at a press conference.
EU foreign ministers on Thursday approved sending a military training mission to Mali.
