Britain's Prince William on Thursday visited Jerusalem's al-Aqsa mosque compound and Judaism's Western Wall at the foot of the hilltop holy site at the heart of the Israeli-Palestinian conflict.
The visit comes 70 years after British forces withdrew from the Holy Land leaving behind the divisions that remain to this day.

The Duke and Duchess of Cambridge, as the couple are officially known, drove from their home at Kensington Palace in central London to St Mary's Hospital in west London.
