Governor Mark Dayton, who joined other public officials and community leaders for a meeting at the Dar Al-Farooq Islamic Center in suburban Minneapolis on Sunday, described the bombing attack at the mosque on Saturday as “so wretched” and “not Minnesota”.

“This is an act of terrorism,” he said, at a press conference. “This is against the law in America.”

Like other US mosques, the center in Bloomington, just south of Minneapolis, occasionally receives threatening calls and emails. But leaders said they were more frightened after the weekend attack, in which an explosive shattered windows and damaged a room as worshippers prepared for morning prayers.

“We feel like it’s much deeper and scarier than like something random,” Mohamed Omar, the center’s executive director, said on Sunday. “It’s so scary.”

No one was hurt in the blast, which happened around 5am on Saturday. Windows of the imam’s office were shattered, either by the blast or by an object thrown through them. The FBI is seeking suspects and trying to determine whether the incident was a hate crime.

Besides serving as a place of worship and community center, the mosque has a fitness center, gymnasiums for boys and girls, a football field and adjoins a city park, Omar said. He estimated the mosque holds up to 300 worshippers for Friday prayers.

The community center also hosts computer classes, a basketball league, religious classes, lectures and other events. “It’s a place that a family can come and get everything they need,” Omar said.

The mosque opened in 2011 at the site of a former elementary school in the suburb of about 85,000 and serves people primarily from the area’s large Somali community. Minnesota is home to the largest Somali community in the US, roughly 57,000 people, according to the latest census figures.

Some residents opposed the center and complaints have been made about parking, noise and traffic, the Star Tribune reported. Omar said the center gets along with “92, 93%” of its neighbors.

While the mosque has received threatening calls and messages, deputy Bloomington police chief Mike Hartley said on Sunday he was unware of any hate crimes reported at the center.

Saturday’s bombing comes amid a rise in reports of anti-Muslim incidents in the US, including arson attacks and vandalism at mosques, harassment of women wearing head coverings and bullying of schoolchildren. Recently in Minnesota, an Islamic cemetery in Castle Rock Township reported it had been vandalized with spray painted profanities and swastikas.

The US Department of Homeland Security said in a Saturday statement on the Bloomington explosion it “fully supports the rights of all to freely and safely worship the faith of their choosing and we vigorously condemn such attacks on any religious institution”.

The reward for information leading to an arrest or conviction has grown to $24,000, said Asad Zaman, director of the Muslim American Society of Minnesota. The Minnesota chapter of the Council on American-Islamic Relations, or Cair, said its national office was urging Islamic centers and mosques to step up security.

“If a bias motive is proven, this attack would represent another in a long list of hate incidents targeting Islamic institutions nationwide in recent months,” said Amir Malik, the local chapter’s civil rights director.
