Nigerian troops say they have beaten the Boko Haram militants who have been waging a long and bloody insurgency aimed at establishing an Islamic caliphate in the north of the country.
Officials have been accused in the past of exaggerating the scale of success against the Islamist terror group, however. So is this another premature claim? The Week looks at the facts.
What is Boko Haram and what has it done?

Boko Haram – which roughly translates as “Western education is forbidden” – was founded in 2002 in the city of Maiduguri. After initially allying with Al-Qaeda, it switched allegiance to Islamic State in 2015.
The insurgency began in earnest in 2009 and has been concentrated in north-eastern Nigeria, but attacks have also extended into neighbouring Cameroon and Chad.
"I can confidently state that we have succeeded in defeating the Boko Haram terrorists," Lieutenant General Tukur Yusuf Buratai told PM News Nigeria in early July.
"We have chased away the terrorists and recaptured all the hitherto held territories, rescued over 20,000 [people] abducted by them including some of the Chibok schoolgirls," he added.
But in a BBC HardTalk interview, Buratai conceded that the militant group has not been completely eliminated.
What about the government?
President Muhammadu Buhari made a similar statement in 2015, telling the BBC that Nigeria had "technically won the war" against Boko Haram as it could no longer mount "conventional attacks" against security forces or population centres.
However, local lawmakers have accused Buhari's government of "deceiving Nigerians with stories of defeat of [the] insurgents",
"If indeed Boko Haram was already defeated, where are those suicide bombings and attacks coming from?" Governor Ayodele Fayose, of Ekiti State, said in January.
What are the facts?
Nigeria witnessed a general downward trend in violence during 2016, according to the Armed Conflict Location & Event Data Project (ACLED), which tracks civil unrest across Africa.
The battle against Boko Haram "turned decisively in the state's favour" from February, when government forces killed or captured a large number of militants. This paved the way for them to win back significant amounts of territory from the insurgent group in March and April, it reports.
This was done with the help of a strong regional coalition – made up of troops from Nigeria, Cameroon, Chad and Niger – as well as a crackdown on corrupt military officials.
"This trend would continue throughout the year, albeit at lower levels, and culminate in the important strategic and symbolic victory of clearing Boko Haram out of the Sambisa Forest, their primary stronghold, in mid-December 2016," ACLED says.
But the group has shown signs of resurgence in recent months, launching a spate of deadly bombings in the north-east, including an attack on the University of Maiduguri.
By the end of June 2017, Boko Haram had carried out 43 attacks, resulting in 200 civilian deaths, according to reports from SBM Intel, an Africa-focused market intelligence firm.
"As it has lost territory, Boko Haram [has] changed strategy, and has refocused on its ability to carry out suicide bombings and quick raids on rural communities," says the report, published this month.
Boko Haram has lost much of the territory it claimed during the early days of its insurgency. However, the recent wave of suicide bombings suggest the fight is far from over.
