Over 400 witnesses passed out Friday at a Jehovah’s Witness convention in Angola after they were attacked with toxic gas.
About 7,000 worshippers were at the venue on the outskirts of Luanda for the weekend-long convention, a local news source, Portal de Angola reports.
At least 43 victims were rushed to the hospital. No deaths have, however, been recorded.
A witness, Abraham Kituxi, told Portal de Angola that his sister-in-law was one of the first to collapse after telling him that she had smelled something foul.
More people began collapsing right after, creating chaos and panic at the venue.
Police and firefighters were called to the scene to assist in sending the victims to the hospital.
Meanwhile, three people have been arrested over the incident, with four others at large.
Police have not been able to identify the toxic substance but indicated that it was in containers of 750 thousand liters spread throughout the venue.
