MUMBAI, India (CNN) -- An Indian official said the coordinated terrorist attacks that killed at least 183 people in nine sites across Mumbai this week could have been much worse. An Indian soldier carries his rifle outside the Taj Mahal Hotel on Saturday in Mumbai, India. "We found bullets with them, hand grenades, bombs," R.R. Patil, deputy chief minister of Maharashtra state, said at a news conference. "Based on our investigation, we believe they had planned to kill 5,000 people." Indian authorities also were investigating whether some of the attackers may have gotten away, blending into Mumbai's 18 million residents.
