Reuters journalists arriving after the blasts saw pools of blood and discarded shoes at the site, a clothing market in Tayaran Square in the centre of the city. Health authorities said at least 110 people had been wounded.
"One (bomber) came, fell to the ground and started complaining 'my stomach is hurting' and he pressed the detonator in his hand. It exploded immediately. People were torn to pieces," said a street vendor who did not give his name.
