KENYA, Nairobi : (FILES) Rescuers work to help survivors amid the devastation brought in by a bomb explosion in Al-Qaeda’s first major international attack near the US embassy and a bank in Nairobi on August 7, 1998 that killed at least 60 people, including eight Americans, and left more than 1,000 injured. US President Barack Obama said on May 1, 2011 that justice had been done after the September 11, 2001 attacks with the death of Al-Qaeda mastermind Osama bin Laden, but warned that Al-Qaeda will still try to attack the US.
