(CNN) — German Chancellor Angela Merkel fractured her pelvis in a skiing accident in Switzerland over the holidays, her spokesman told reporters Monday.

Merkel was cross-country skiing when the accident occurred. Spokesman Steffen Seibert did not disclose the date of the incident, but said her injuries are not thought to be serious and it is thought she will make a full recovery.

Merkel, who has been Chancellor of Germany since 2005, will need aid to walk over the next few weeks and will be canceling some of her commitments, Seibert said.

Merkel’s Christian Democratic Union (CDU) said it will delay its party retreat, originally slated for January 10-11, as a result of her accident.
