Relatives are flying to Nepal to join the continuing search for 33 British citizens who are still unaccounted for following the devastating floods in the country.

The brother of Neetu Goyal Tiwari, one of the British nationals missing since Wednesday, has implored officials to locate his sister.

Naresh Goyal, visibly emotional, implored the BBC for assistance in finding her.

On Friday, Nepalese authorities released a list of 573 tourists whose whereabouts remain unknown, and despite concerns about another wave of flooding, search operations have persisted.

To assist with the situation, the United Kingdom is dispatching a rapid response unit to Nepal to aid British citizens affected in the area.

This specially trained crisis response team is anticipated to arrive in Kathmandu on Saturday, following Prime Minister Andy Burnham's promise of £5 million in humanitarian aid for relief and recovery efforts.

As rescue operations continue in the wake of the catastrophe, which claimed at least 538 lives, information about those missing is gradually emerging.

Tiwari, aged 51, had journeyed to Nepal to participate in the Kailash Mansarovar Yatra pilgrimage, which her brother Naresh Goyal informed the BBC was "her lifelong ambition."

She flew from London to Delhi before continuing to Kathmandu on August 14th with a group affiliated with the Isha Foundation, a spiritual organization.

Tiwari was scheduled to return to India on Thursday to meet her brother and parents, but the family is now desperately seeking answers regarding her disappearance.

Goyal stated that they had contacted every helpline provided by the Indian government and also reached out to the British Embassy in Kathmandu.

He appealed for help in locating her, his voice faltering, adding that they were all extremely worried.

Neetu's husband, Shantanu, confirmed that she was at the Gyirong checkpoint when the floods hit, leading to China coordinating the search efforts for her.

Anant Patel expressed concern for his parents, Bipin and Mala, who have gone missing while undertaking a pilgrimage.

Anant Patel informed BBC Your Voice that he is still awaiting news regarding his missing parents, Bipin and Mala Patel, who are from Coventry.

The 29-year-old believes his parents, also on a pilgrimage, entered Tibet from Nepal just before the landslide struck the Gyirong border crossing.
