Harris and Walz hold first rally together

Democratic supporters at a rally in the United States have given a raucous welcome to Kamala Harris and her new running mate for November's presidential election, Tim Walz. The Minnesota governor used his first speech to attack Donald Trump -- saying he was too selfish to serve Americans.

Also, the Nobel Peace Prize winner, Muhammad Yunus, has been named as the head of Bangladesh's interim government. The economist's appointment was announced a day after Sheikh Hasina was ousted as prime minister.
