1. President Trump, using Twitter posts as geopolitical broadsides, promised that missiles would be fired at Syria in response to a suspected chemical weapons attack and proclaimed relations between the U.S. and Russia to be worse than ever.

Mr. Trump also warned, in reference to President Bashar al-Assad of Syria, that the Kremlin should not be allied with a “Gas Killing Animal who kills his people and enjoys it!” Here’s what we know about the apparent attack, which took place near Damascus.
