After the partial collapse of a twelve-story apartment building in the US state of Florida, the death toll has risen again.

Six more victims were found on Wednesday, said the mayor of the Miami-Dade district, Daniella Levine Cava, on Wednesday evening (local time) at the accident site in Surfside near Miami.

The number of deaths has risen to 18 – including two children between the ages of four and ten. 143 people are still missing.

The building near the beach with around 130 residential units had partially collapsed on Thursday night. The misfortune surprised people in their sleep. Since then, a desperate search for possible survivors has been going on.
