Two cousins from Sheffield may be among those killed in the terrorist attack on a nightclub in Bali.

The parents of Natalie Perkins, 20, and Laura France, 18, have issued a statement saying the pair are "missing, presumed dead".

Natalie and Laura were on the Indonesian island while travelling to Australia for a holiday.

Thirty-three Britons are thought to be among the 188 who died in Saturday's bombing.

Possible sighting

In the statement, issued through South Yorkshire Police, George and Sandra Perkins and Sharon and Tony France expressed their sadness at the news coming from Bali.

The statement said: "Both Natalie and Laura had completed studies in Sheffield and were taking this trip before pursuing their respective careers and further education."

Both women's parents said they had little hope that their daughters would be found alive.

Their fears were increased when a survivor of the blast revealed that she had been at the nightclub, in the resort of Kuta, with a group which included two students from Sheffield.

Mary King, from Liverpool, pulled a friend to safety after the bombing, but said that among those she saw dead were the two unnamed students who are believed to be Natalie and Laura.

A family liaison officer from South Yorkshire Police has been assigned to help the families.

Miss France has twin brothers aged 12 while Miss Perkins has a brother, 18, and a 17-year-old sister.
