2. Navy warship collision

The Navy's mourning the loss of seven sailors after a warship collided with a merchant vessel in Japan. The sailors were found in flooded compartments after the USS Fitzgerald, a 10,000 guided-missile destroyer, collided with the 29,000-ton container ship on Saturday. Officials aren't speculating how the incident occurred but the location -- Japan's Izu Peninsula -- sees heavy maritime traffic, with 400 to 500 vessels crossing it daily.

Also this weekend: Seven US service members were wounded in an insider attack by an Afghan soldier at a US camp in northern Afghanistan. It's the second weekend in a row when US forces have been victims of a so-called blue-on-green attack by an Afghan soldier.

3. Iran and ISIS

Iran said it would avenge the recent terror attacks on its soil. And it made good on its word over the weekend. It launched a missile attack targeting ISIS forces in eastern Syria. It's the first time Iran has fired missiles at another country in 30 years. This is a real escalation in the Syrian conflict because Iran's a big backer of the Syrian regime. So the strike helps President Bashar al-Assad too. ISIS claimed responsibility for the terror attacks almost two weeks ago on Iran's Parliament building and a shrine that left 16 people dead.
