10 missing from USS John S. McCain after ship collision

Per the Associated Press:

• "The Navy says 10 sailors are missing and five were hurt in the collision [of the USS John S. McCain and the Liberian-flagged Alnic MC] in waters east of Singapore and the Strait of Malacca early Monday."
• "Singapore sent tugboats and naval and coast guard vessels for the search and rescue effort... Osprey aircraft and Seahawk helicopters from the USS America were assisting in the search."
• President Trump's response, per WH pool: "Thoughts & prayers are w/ our @USNavy sailors aboard the #USSJohnSMcCain..."

Why it matters: "The collision was the second involving a ship from the Navy's 7th Fleet in the Pacific in two months. Seven sailors died in June when the USS Fitzgerald and a container ship collided in waters off Japan."
