When police attempted to storm an apartment in the northern Paris suburb of St Denis early Wednesday morning, a woman wearing an explosive suicide vest detonated her device, the Associated Press reports, killing herself and another man. Seven other people were arrested.

In addition to the woman who detonated her suicide vest, a man in the apartment died when a grenade exploded, the New York Times reports. Five men in the apartment were arrested and a man and a woman nearby were also detained.

An unnamed senior police official told the AP that he believed Abdelhamid Abaaoud, thought to have been in Syria, was inside the apartment. The office of the Paris prosecutor confirmed to the Times that Abaaoud was the target of the raid, but it is still unclear whether he was actually in the apartment.

The Guardian reports that one of those arrested was the building’s landlord.

Five police officers were lightly wounded. A 7-year-old police dog named Diesel was killed.
