COLOMBO, APRIL 24 (SPA) - FOUR PEOPLE WERE SHOT DEAD IN FRESH SRI LANKAN VIOLENCE ON MONDAY, WHILE THE KILLING OF SIX SINHALESE FARMERS BY SUSPECTED TAMIL TIGER REBELS THE PREVIOUS DAY RAISED FEARS OF MORE ETHNIC RIOTS. SOME 100 PEOPLE HAVE DIED IN JUST OVER TWO WEEKS AFTER A SERIES OF SUSPECTED TAMIL TIGER AMBUSHES ON THE MILITARY WERE FOLLOWED BY ATTACKS ON TAMIL CIVILIANS. BOTH SIDES SAY THEY ARE STILL WORKING TOWARDS TALKS THAT WERE SCHEDULED FOR LAST WEEK IN SWITZERLAND, BUT ARE NOW INDEFINITELY POSTPONED, REUTERS REPORTED. --SPA 1314 Local Time 1014 GMT www.spa.gov.sa/355799
