Dozens of people have been arrested so far in connection with the attacks.Meantime, Sri Lanka’s president has asked the defense secretary and national police chief to step down. This marks a dramatic internal shake-up after security forces shrugged off intelligence reports warning of possible attacks before the bombings, the president’s office said.The president announced on Wednesday that he planned to change the head of the defense forces within 24 hours.The scale of the bloodshed recalled the worst days of Sri Lanka’s 26-year civil war, in which the Tamil Tigers, a rebel group from the ethnic Tamil minority, sought independence from the Buddhist-majority country. During the war, the Tigers and other rebels carried out a multitude of bombings. The Tamils are Hindu, Muslim and Christian.
