The sinking of an Iranian warship Tuesday by a U.S. submarine thousands of miles from the war zone in international waters raises questions about whether the attack was legal under the rules of war.

Libyan authorities say a Russian-flagged tanker carrying liquefied natural gas exploded and erupted in flames before sinking in the Mediterranean Sea off the North African country's coast.

Sri Lankan authorities said bodies of 87 sailors had been recovered from the warship, while 32 people had been rescued. | World News
