Dozens of people are feared dead in two large explosions near to where former Pakistan Prime Minister Benazir Bhutto was being welcomed home.
Bhutto’s truck had just passed when the blasts happened in Karachi, just hours after she ended her eight-year exile.
Hundreds of thousands of people had lined the route to see her. Militants linked to al Qaeda, angered by her support for the US war on terrorism, had threatened to assassinate her.
