Here's a look at key Syria developments around the world Tuesday amid heightened tensions over potential military action:Israel carried out a joint missile test with the U.S. in the Mediterranean Sea as Washington considers sea-launched strikes against Syria. The Defense Ministry said it and the U.S. Defense Department carried out a "successful test" in the Mediterranean and on an air force base in central Israel. Five U.S. Navy destroyers are in the eastern Mediterranean waiting for a launch strike order. The destroyers are armed with dozens of Tomahawk cruise missiles, which have a range of about 1,000 nautical miles (1,151 miles, 1852 kilometers) and are used for deep, precise targetingCongress will holding its first public hearing about U.S. plans for military intervention in Syria as Obama tries to convince skeptical Americans and their lawmakers about the need to respond to last month's alleged sarin gas attack outside Damascus.

A classified briefing open to all members of Congress will also take place.The U.N. refugee agency said more than 2 million refugees have fled Syria's violence in an exodus that shows no sign of letting up and could destabilize neighboring countries. Antonio Guterres, head of the Office for the U.N.

Security Council.Foreign Minister Luiz Alberto Figueiredo said any military intervention against Syria would be seen as a violation of international law unless the U.N. Security Council gives approval or if the intervention is for self-defense coupled with a U.N. resolution. He said late Monday that those scenarios are "not what we have today."
