A woman from Bradford is understood to be among the victims of a stampede in Saudi Arabia in which more than 700 people have been killed.
A further 800 people were injured in the disaster which happened during the annual Hajj pilgrimage.
About two million people are taking part in this year's pilgrimage, which began on Tuesday.
The Bradford Council for Mosques said an emergency hotline was being set up for relatives of the hundreds of people from the city who have travelled to Mecca.
Zulfi Karim, from the council, said it was estimated between 5,000 to 7,000 people from Bradford were in the area at the moment.
He said: "We are hoping and praying for those people who are out there. There are a lot of people from the city out there at the moment and we are liaising with the Foreign Office and the tour companies.
"We are also setting up a special emergency hotline tonight so people can get information."
Foreign Secretary Philip Hammond has expressed sadness at the "enormous loss of life in Mecca" after hundreds were killed in a crush during the Hajj pilgrimage.
It is currently unclear whether any Britons were among those killed and injured, and Hammond said Foreign Office staff were "in close contact with the Saudi authorities and tour operators, and are checking hospitals and other locations to urgently gather information about British nationals who may require assistance."
"We are also deploying further staff from the region to bolster our response," he said.
I was saddened to hear of the enormous loss of life in Mecca. My thoughts are with families and victims at this difficult time. Such a significant tragedy will affect Muslims across the world who take part in the Hajj pilgrimage.
Anyone concerned about British nationals attending the pilgrimage is advised to telephone the embassy in Riyadh or tweet the FCO Twitter account.
A special plaque will be unveiled in Bradford today to celebrate 120 years of Rugby League.
The city has been chosen as one of the special national sites to commemorate key events in the history of rugby league, as it was the home of the first Northern Union champions, Manningham.
On August 29, 1895 at a historic meeting at the George Hotel in Huddersfield, 22 clubs broke away from the RFU to form the Northern Union which became Rugby League.

Bradford has played a significant role in the history and development of Rugby League. It is fitting that this contribution should be recognised with a commemorative blue plaque in this special year for our sport. As we celebrate our heritage we acknowledge the special role Manningham has played in the history of Rugby League.

Supermarket giant Morrisons has announced that its Northallerton store in North Yorkshire is among the 11 it is planning to close across the country.
The closure announcement was made last week, following the revelation that half year profits to August had fallen by nearly 50% compared to the same period last year. But the Bradford-based chain did not disclose which stores were to go, saying the decision had only just been announced to staff.
The full list has now been revealed, with most of the closures in the North of England, Morrisons' traditional stronghold. Supermarkets in Salford, Manchester and Sunderland will all close, while the Midlands, the West Country and London have been hit too. The move will result in a one-off cost of £20 million and is in addition to the closure of10 supermarkets which shut earlier this year.
We have looked extremely carefully at whether the stores can be turned around but unfortunately we cannot see a way of making them viable. We are therefore proposing their closure. We are consulting with colleagues and unions and we will be discussing how to reduce redundancies and redeploy colleagues around our business.
Bradford City boss Phil Parkinson has signed a new three-year contract as manager of the West Yorkshire club.
Parkinson, whose original deal was due to expire at the end of this season extends his association with the football club until the end of the 2017/2018 campaign.
Assistant Manager Steve Parkin, Head of Sports Performance Nick Allamby and Goalkeeper Coach Lee Butler have also agreed new contracts with the football club until the end of June 2018.
This club is clearly moving in the right direction under Phil and the current management team, and it is important we keep the wheels moving forward.
The momentum has been with us since Phil arrived at the football club and he deserves this new contract.
I'm very proud of my record here at Bradford City so far but I have been very lucky to receive the backing I've had from the chairmen and the board.
You always need good people around you as a manager, and I think we have a very good team both above me at boardroom level and around me at the training ground.
