Sectarian blasts target Afghan Shi'ites, kill 59

KABUL (Reuters) - A suicide attack killed dozens of Shi'ite Muslims at a crowded Kabul shrine on Tuesday and four died in a smaller blast in a key northern city in the worst sectarian violence Afghanistan has seen since the fall of the Taliban.

The Kabul bomb was the deadliest in the capital since 2008, and punctured any lingering sense of optimism from a conference on Monday where Western allies made firm but not specific promises to support Afghanistan after troops leave in 2014.
