Geopolitics and oil prices

From the BBC World Service: We're tracking volatility in global oil prices following U.S. attacks on Iran over the weekend. There's a renewed focus on a key oil transport waterway, the Strait of Hormuz, which Iran’s parliament voted to shut down. U.S. Secretary of State Marco Rubio has also called on China to influence the situation there. Plus, the Spanish city of Seville carried out a pilot project naming heat waves to raise public awareness and better prepare local economies.
