Iran vows revenge for Supreme Leader's death, Human trafficking in Northern Ontario, Testing sunscreen effectiveness, and more

The United States and Israel hit Iran with a fresh wave of attacks Sunday - a day after the assassination of the country's Supreme Leader, Ayatollah Ali Khamenei. Iran has vowed retaliation - continuing its own airstrikes on a number of countries in the region. An interim council is running the country. But Khamenei's death, along with the killings of several senior Iranian figures, has created uncertainty about Iran's future.Also: In a ten year period ending in 2024, Canada had more than five thousand reported cases of human trafficking. And the Northwestern Ontario city Thunder Bay had the highest average annual rate. Many of the victims often don't know they're being groomed. But those who have gone through it are playing a key role in trying to protect those at risk.And: Skin cancer rates are on the rise in Canada. But as people turn to sunscreen for protection, the number on the bottle isn't always trustworthy. The CBC Marketplace team sent samples from one brand of sunscreen to several labs for testing. And the results they got back were wildly different.Plus: More reaction to the conflict in Iran, the effect of motherhood on orcas, and more.
