However, rescue worker Sani Kakale said: "In my presence, 42 dead bodies were taken to hospital and 68 injured".
A local resident, Garba Habu said "A boy of about 18-19 -years wearing a suicide vest was said to have entered the mosque along with other worshippers".
In a tweet on its handle, the presidency wrote: "Today's suicide bomb attacks in Mubi, Adamawa State, targeting a Mosque and Market, are tragic & despicable".
Witness Abdullahi Labaran said the first bomber had mingled with worshippers and detonated his explosives shortly before prayers began.
The government has said since December 2015 that Boko Haram has been defeated.
The Executive Secretary of Adamawa State Emergency Agency, Mr Haruna Furo also confirmed the blast but said there was no details for now.
The attacks targeted a mosque and a market in Mubi and blame has been pointed to the Boko Haram extremist group.
This is the second attack at a mosque in Mubi in six months, AP reported.
Separate suicide bomb blasts struck Nigeria's Mubi town, which is in the north-east part of the country.
But it has been peaceful since the Nigerian military and civilian militias ousted recovered the town, which is a commercial hub and host of the Adamawa State University.
Nigerian President Muhammadu Buhari has been in the United States this week and met his U.S. counterpart Donald Trump, who pledged more support in the fight against Boko Haram. That area is not far from the Sambisa Forest area where the extremists had a stronghold.
Suspicion immediately fell on Boko Haram, the group that has left at least 20,000 dead since 2009.
