Sri Lanka's Tamil Tiger rebels said on Thursday they will attend peace talks in Switzerland, surprising diplomats who had taken recent attacks to mean the meeting was off. Repeated suspected rebel attacks on government forces and ethnic violence have killed more than 40 people over the past week, sharply raising fears of a return to civil war. "The Geneva talks will happen," head of the rebel peace secretariat, S Puleedevan, told Reuters by satellite phone from Kilinochchi, the de facto rebel capital. "But the dates will have to be moved by a bit. We will go once we have met our eastern commanders from April 15 to 22."
