By Katya Golubkova and Alexander Winning MOSCOW (Reuters) - Holding placards declaring "I am not afraid", thousands of Russians marched in Moscow on Sunday in memory of Kremlin critic Boris Nemtsov, whose murder has widened a split in society that some say could threaten Russia's future. Families, the old and young walked slowly, with many carrying portraits of Nemtsov, an opposition politician and former deputy prime minister who was shot dead while walking home from a restaurant in central Moscow on Friday night. "If we can stop the campaign of hate that's being directed at the opposition, then we have a chance to change Russia. If not then we face the prospect of mass civil conflict," Gennady Gudkov, an opposition leader, told Reuters before the march.
By Matt Spetalnick and Dan Williams WASHINGTON/JERUSALEM (Reuters) - Signs are growing that Israeli Prime Minister Benjamin Netanyahu's planned speech to Congress against a possible nuclear deal with Iran could damage his country's broad alliance with the United States. The right-wing leader's acceptance of a Republican invitation to address the U.S. legislature already brought Netanyahu's long-strained relations with President Barack Obama to a new low due to the overture's partisan nature. Israel fears that Obama's Iran diplomacy, with an end-of-March deadline for a framework nuclear agreement, will allow its arch foe to develop an atom bomb. Previously Israel has always been careful to navigate between the Republican and Democrat camps.
