Fireworks and extreme heat caused several injuries on Independence Day weekend in Anne Arundel County. One boat exploded, and another was in a hit-and-run crash over the holiday weekend.

A gargantuan fireworks detonation likely caused by someone smoking a cigarette obliterated several homes and injured five people in an island community in Washington state this week, according to authorities.

A family was shooting off fireworks on a private dock when some other fireworks ignited and detonated early, according to the coroner's office.
