Parisians are putting flowers in the bullet holes left from attacks

Parisians went to many of the sites where so many had died, including the Bataclan theater, where attackers gunned down dozens of hostages, and the restaurants which other attackers targeted. Some left roses in the bullet holes left by the assault.

Paris is in the midst of a three-day period of national mourning. The investigation into the attacks continues. Below, see some of the images of a city still in shock.
