KUWAIT CITY, (AP) — The death toll in a fire at a Kuwaiti wedding celebration has risen to 45 women and children, an official said Tuesday, as authorities questioned a suspect they say confessed to starting the blaze.

Fire department chief Brig. Gen. Jassem al-Mansouri said four more victims died in hospital and six remained in critical condition.

Authorities announced Monday they had a suspect in custody who confessed to starting the fire for “personal reasons,” but they did not provide any details about that person’s identity.

Kuwaiti newspaper reports have said she is the groom’s ex-wife or first wife. Islam allows men to take up to four wives.

Calls to the Interior Ministry for comment on the reports were unanswered Tuesday.

Saturday’s blaze in the tribal area of al-Jahra, west of Kuwait City, destroyed the wedding tent where guests were celebrating in just three minutes. It was Kuwait’s worst fire in almost four decades.
