A fresh gun battle erupted in Nigeria between militants and troops near the airport of the northeastern city of Maiduguri, a security source and nearby resident said Sunday evening.
"I can hear sporadic gun shots and bomb explosions, I am sure the boys are back to retaliate for what was done to them this morning," Bello Muhammad, who lives about 300 metres (yards) from the airport, told Reuters.
Suspected Boko Haram insurgents launched an attack on the outskirts of Maiduguri, including the airport that is used by military and civilian aircraft, on Sunday just after midnight but were repelled by the army in the early afternoon.
Suspected Boko Haram militants launched a midnight ambush in the Nigerian city of Maiduguri, government and police sources said.
A Reuters witness said shelling could still be heard this morning. The militants began the attack at the edge of the city in the Njimtilo area.
The city is the capital of Borno state.
A man claiming to be the leader of Islamist group Boko Haram has appeared in a video to claim responsibility for a deadly attack on the Nigerian town of Baga.
The man said to be Abubakar Shekau said the attack "is just the tip of the iceberg" as he warned that the group has enough weapons to "annihilate Nigeria, not to mention Cameroon".
Local officials put the death toll in Baga as high as 2,000 but the Government said 150 people were killed when insurgents stormed a military base in early January.
The bearded man is surrounded by masked fighters in the video, who show off an array of weapons allegedly taken from the base during the attack.

A suicide bomber drove a car packed with explosives into a busy bus station in the northeast Nigerian town of Potiskum on Sunday, killing four people and wounding 35, police said.
There was no immediate claim of responsibility for the attack, which bore the hallmarks of Islamist militant group Boko Haram.
"The information I have is that the car was pretending to be scouting for passengers," Yobe state police commissioner Danladi Marcus told Reuters news agency by telephone.
"Five people including the bomber were killed in the attack with about 35 others receiving treatment for various injuries at Potiskum General Hospital."

Two suspected child suicide bombers, both girls, have reportedly blown themselves up in a market in north-east Nigeria.
Witnesses claimed girls as young as 10 attacked the market selling mobile handsets in the town of Potiskum in Yobe state on Sunday.
Another witness claimed two ambulances had arrived at the scene and were picking up bodies although the number of fatalities was still unclear.
The latest incident comes a day after a young suicide bomber killed at least 16 people in the Nigerian city of Maiduguri.
Yobe is frequently targeted by extremist group Boko Haram who have claimed responsibility for a number of recent attacks in the country.
Islamist Boko Haram militants mounted an attack on a city on the northern border of Nigeria that may have killed thousands, terrorism experts and the US government have said.
According to NBC News, survivors of the initial assault fled into the waters of nearby Lake Chad, where some drowned and others remain marooned on small islands, under menace from wild animals - including hippos.
In an interview with NBC News on Thursday, Ahmed Zanna, a local senator, said the militants razed Baga and the other communities: "These towns are just gone, burned down. The whole area is covered in bodies."
Zanna said that more than 2,000 people were unaccounted for, and residents who fled the towns reported the killing had been going on since Boko Haram overran a nearby military base last weekend.
American experts say such reports are credible and that officials from Nigeria's central government, who have put the body count in the hundreds, are prone to underestimating death tolls.
A US counter-terrorism official said the tally of 2,000 deaths "may not be that far off."
John Campbell, a former ambassador to Nigeria who is now a senior fellow at the Council on Foreign Affairs, also agreed that the estimate of 2,000 was "not unreasonable," given the "magnitude" of the attack.
"We have to go by previous pattern and experience," said Campbell. J. Peter Pham, director of the Atlantic Council Africa Center, also told NBC News he believed the number was "credible."
All three, however, warned NBC News that getting an accurate death total was nearly impossible.
The death toll from an explosion that hit the central mosque in Kano, northern Nigeria, has risen to "at least 81", Reuters have reported, citing hospital sources.
Police earlier put the figure at 35.
