Many of the papers lead with the news that the man suspected of a suicide bombing in Sweden on Saturday had links to the UK.
Taimour Abdulwahab al-Abdaly, 29, has been named by many as the man who died in the attack.
The Daily Mail says he was radicalised while studying in Luton, a town it describes as "a hotbed of terrorism," and says he had been in the UK for much of the last decade.
It thinks it raises new questions about admissions to British universities.
The Daily Telegraph says Abdaly was in the UK two weeks ago, and that his wife and children still live here.
One of his lecturers, Tim Paine, tells the Times that Abdaly once told him he was becoming "stressed-out" about the invasion of Iraq.
