The man accused of trying to kill Danish cartoonist Kurt Westergaard and December's Mogadishu suicide bomber were in Sweden together, according to a Swedish newspaper.

The 28-year-old Somali who is charged with attempting to kill the Danish cartoonist Kurt Westergaard and the man suspected of being the suicide bomber who killed some 24 people in Mogadishu several weeks ago were in Sweden together last year, according to the Swedish newspaper Expressen.

The Somali believed to have been the Mogadishu bomber, who killed three government ministers in the attack on a graduation ceremony on Dec. 3, is also thought to have lived in Denmark for some time.

The Expressen report, citing sources in the Somali community in Sweden, says the two men were in the country to collect money for Somalia's al-Shabab organization, which controls much of southern Somalia.

"We are following this very closely and have extensive cooperation with the Danish Security and Intelligence Service," Sweden's Intelligence Service (SAPO) spokesman Patrik Peter tells the newspaper.
