There's been a warm welcome in Pakistan for Crown Prince Abdullah of Saudi Arabia, who's arrived in Lahore on the last leg of a world tour.

He was greeted by President Rafiq Tarar and the Prime Minister, Nawaz Sharif.

During his three-day stay, Prince Abdullah will have talks with Mr Sharif which are expected to cover the situation in Afghanistan and other regional issues.

It's also thought that Pakistan will press for economic help from Saudi Arabia, to try to overcome the impact of international sanctions which followed Pakistan's nuclear tests.
