The 89-year-old monarch and her husband Prince Philip have sent their "deepest sympathy" to Nepali president Ram Baran Yadav and those affected by the natural disaster, which is estimated to have killed around 4,000 people when it struck on Saturday (25.04.15) morning.

In a message to the president, she said: "I was shocked to hear of the appalling loss of life and injuries caused by the earthquake.

"My thoughts and prayers are with the victims of this disaster and with those bereaved and affected.

"Prince Philip joins me in extending our deepest sympathy to you and the Nepali people. The thoughts of everyone in the United Kingdom are with the families of all those caught up in this terrible event."

The queen's message came as a number of stars have appealed for support for relief efforts.
