Tensions that had been building for months in Lebanon erupted in violence Thursday in Beirut. Several people were killed at a protest being held by Hezbollah supporters.

"If we didn't lead this fight, nobody would," says a Beirut resident whose 3-year-old daughter was among the 217 killed in the blast. An official investigation has stalled. No one has been prosecuted.

It was a decision that appalled and angered Syrian opposition groups and international medical organizations. On May 28 Syria was appointed to the World Health Organization's Executive Board.
