No information about the incident was initially released by authorities, leading to criticism from online users.
A jury on Wednesday convicted the leader of an Illinois anti-government militia group of civil rights and hate crime charges in the 2017 bombing of a Minnesota mosque.
Michael Hari, 49, was found guilty on all five counts. They include damaging property because of its religious character, forcibly obstructing the free exercise of religious beliefs, conspiracy to commit felonies with fire and explosives, using a destructive device in a crime of violence, and possessing an unregistered destructive device.
Prosecutors outlined Hari’s hatred for Muslims as his motivation for the bombing during the trial, citing anti-Islam excerpts from Hari’s manifesto known as The White Rabbit Handbook, named after his militia group.
The number of far-right militias increased during the course of former President Barack Obama’s time in office, according to advocacy group the Southern Poverty Law Center (SPLC). The total number has decreased since Trump’s election in 2016, but the SPLC in 2019 recorded 181 active militias in the US.
Prosecutors presented evidence to jurors that included phone records and testimony of federal investigators who tracked Hari down to Clarence, Illinois, a rural community about 190km (120 miles) south of Chicago where Hari and two co-defendants lived after a seven-month investigation.
The testimony by those co-defendants, Joe Morris and Michael McWhorter, portrayed that Morris viewed Hari as a father figure, and that Hari instructed them to throw the pipe bomb into the Dar Al-Farooq Islamic Center as Hari waited in the car after driving up from Illinois in a truck he rented.
Morris, who – along with McWhorter – pleaded guilty in January 2019 to their role in the attack, testified that Hari said the mosque trained ISIL fighters.
The bombing took place on August 5, 2017, when the pipe bomb exploded in the imam’s office as worshippers gathered for early morning prayers.
No one was hurt in the explosion, though community members were shaken by the incident and the mosque’s executive director testified last month that it has led to diminished attendance due to fear.
Defence lawyers argued that prosecutors failed to produce forensic evidence putting Hari at the suburban Minneapolis mosque on the day of the attack and attempted to discredit Morris and McWhorter with what they said were inconsistencies in their testimony. Hari refused to testify in his own defence.
Prosecutors deflected the defence’s claims about the lack of evidence, saying Hari’s past as a former sheriff’s deputy who investigated crimes meant he knew not to leave forensic evidence behind.
