Fighting between M23 rebels and the army continued for a second day Tuesday, May 21, 2013, near Congo’s eastern provincial capital of Goma, in clashes that have so far killed 20 people, all of them either soldiers or rebels, officials said. Peace talks reached a dead end in recent weeks, and after a six-month lull, the Congolese army and the M23 started fighting again on Monday. (AP Photo/Jerome Delay, File)
