We begin with the terrifying bombing in Boston along with the heart-breaking news of a terrible deadly explosion in Texas; we report on the seemingly unstoppable Iranian and Korean development of nuclear weapons and Israel’s warnings of a pre-emptive strike to prevent Iran; China’s investments in Europe surge while the U.S. and Germany hold differing economic views; President Obama once again snubs the U.K.; the new pope takes control; and we conclude with reporting about earthquakes–large and small–from diverse parts of the world.
