BANGKOK (Reuters) - Evacuated residents warily began returning to their homes on Bangkok's outskirts on Thursday after a chemical factory went up in flames earlier this week, as experts called for air and water to be thoroughly tested for any lingering toxic chemicals.

One firefighter died and at least 33 people were injured in Monday's blaze at Ming Dih Chemical.
