LAHORE, Pakistan (AP) — Britain's Prince William and his wife Kate are touring Pakistan's eastern city of Lahore, where they will visit a cancer hospital previously visited by William's mother, the late Princess Diana.

The hospital was started by Pakistani Prime Minister Imran Khan, whose first wife Jemima Goldsmith was a friend of the late princess.

The royal couple played cricket with children and members of Pakistan's cricket team at the National Cricket Academy. Their day began with a birthday party at a charitable organization, SOS Children's Village, and they'll also visit the historic Badshahi mosque.

Since arriving, the royal couple have been advocates for girls' education, visiting a girl's school in Islamabad. They addressed climate change while in Pakistan's northern region, where glaciers are melting at an alarming rate.

They return home Friday.
