No reprieve for those in Vanuatu, with heavy rain worsening devastation following last week's 7.3 magnitude earthquake

Rain poses flooding and land-slip risks, as more than 1000 people have been forced from their homes to sleep in the open.

Save the Children's Lavinia Mahit is in Port Vila and says the damage is overwhelming.

She says everyone in the capital is traumatised, with the rain only adding to the anxiety.
