(CNN) Germany's president Frank-Walter Steinmeier has warned of the fractures in its society -- highlighted by the electoral success of the far-right party Alternative for Germany (AfD) -- on the nation's Day of German Unity.
 Steinmeier  spoke of walls between cities and rural areas  between rich and poor  old and young  and online and offline communities.
They are "walls of alienation  frustration or anger" and behind those walls there is "deep mistrust of democracy and its representatives "  Steinmeier  said.
Without mentioning the AfD by  name  Steinmeier  warned that Germany's progress since 1990  becoming a democratic  peaceful and strong country at the heart of Europe  could be lost if politicians and ordinary Germans do not work together to fight the party's far-right ideology and to respond to the concerns of its supporters.
 Steinmeier  addressed this issue in  his  speech Tuesday  saying many Germans from the former East no longer feel at home in their own country  and question if anyone is looking out for them.
"This desire for a home  a homeland -- we mustn't leave that to the nationalists " said  Steinmeier .
"There must never be a route back to nationalism "  he  insisted  a statement that was met with a sustained ovation.
 Steinmeier  did  however  suggest Germany should consider stricter immigration controls in what can be seen as a bid to draw AfD voters back to the mainstream parties.
Germany should give asylum to those who are eligible   he  said  but must also consider "which forms of and how much immigration we want ... and need."
"Migration should be controlled according to our requirements "  he  continued  insisting that people who come to Germany must learn the language and abide by the country's laws and values. "That cannot be up for discussion."

question:
"I cannot say this strongly enough: We believe the NCAA is simply wrong " Louisville interim President Dr. Greg Postel said in a statement. "We disagree with the NCAA ruling for reasons we clearly stated in our appeal. And we made a strong case - based on NCAA precedent - that supported our argument."
"From Day One  the university has admitted that the actions of the former operations director and any others involved under previous leadership were offensive and inexcusable "  Postel  said in the statement. "That is why  we  apologized immediately  cooperated fully with the NCAA  self-imposed penalties that were appropriate to the offenses and made significant changes to ensure incidents like this never happen again.
—  Postel  estimated the return of up to $600 000 in NCAA Tournament revenue.
"This dark cloud has hung over  our  heads for more than two years  and it has had a negative impact on  our  athletics program   our  fans and the entire university family "  Postel  said. "While  we  disagree with the NCAA's decision  it is time for the university to close this chapter and move forward with a stronger commitment to excellence on and off the court."
 Postel   then-athletic director Tom Jurich and Pitino said last summer they planned to fight the sanctions. Pitino  who repeatedly denied knowing about the activities described in Powell's book  was particularly frustrated with his penalties.
