Washington/BerlincTypeface:> US politician Nancy Pelosi underwent "successful” hip replacement surgery at a US military hospital in Germany on Saturday morning and is now recovering, according to spokesman Ian Krager.

Pelosi, the former speaker of the US House of Representatives, reportedly fell on a flight of stairs while in Luxembourg, according to media reports. Pelosi’s office has not disclosed details about the incident other than that she "sustained an injury during an official engagement.” She was in the small European country as part of a US congressional delegation trip to commemorate the 80th anniversary of the Battle of the Bulge during World War II. Pelosi had been scheduled to attend an event marking the anniversary on Saturday. (DPA)
