Authorities in Canada are investigating whether the killing of a Toronto police officer during the execution of search warrants is linked to a broader series of global terror attacks. Constable Marc Pinizzotto, 43, was killed on Thursday during a dawn search of an apartment building in the west of the city. The search concerned a number of shootings, including one targeting the city’s US consulate in March. A police source stated that investigators are looking into whether the perpetrators belong to a city-wide network of “shooters for hire” that has targeted private homes and buildings owned by a large waste management company. The source also noted that investigators are exploring a potential link to a global terror network that has threatened retribution for US attacks on Iran. According to the source, US court documents suggest an Iraqi national, Mohammad Baqer Saad Dawood al-Saadi, may have claimed responsibility for the Toronto consulate shooting. US prosecutors allege al-Saadi is behind a group called Harakat Ashab al-Yamin al-Islamia, which reportedly works with Iran’s Islamic Revolutionary Guard Corps to attack targets linked to the US and Israel. Police have charged 19-year-old Nicholas Bennett with the first-degree murder of Pinizzotto, while 19-year-old Zara Jabbi remains at large. Ontario’s special investigations unit is investigating the shooting, and a spokesperson stated that four other people were in the apartment unit when an “exchange of gunfire” occurred. The RCMP did not respond to questions regarding a possible connection to global terrorism. Meanwhile, local officials and politicians, including Toronto Mayor Olivia Chow and Prime Minister Mark Carney, have paid tribute to Pinizzotto.
