Boston Marathon bombing

The Boston Marathon bombing occurred on April 15, 2013, when two homemade bombs exploded near the race's finish line, killing three people and injuring over 260. The attack was carried out by brothers Tamerlan and Dzhokhar Tsarnaev, motivated by extremist beliefs. The incident prompted a massive manhunt and heightened security measures at public events. In the aftermath, the marathon became a symbol of resilience, with many participants wearing "Boston Strong" shirts in solidarity. The Tsarnaev brothers were later captured, with Tamerlan killed in a shootout and Dzhokhar sentenced to death for his role in the attack.
