Anxious: People gather in front of Rana Plaza building as rescue workers continue their operations

Bangladeshi police fired tear gas and rubber bullets at anxious relatives as they overcrowded the site of a Bangladeshi collapsed clothes factory building where nearly 300 people were killed. 

At the disaster scene exhausted teams of soldiers, firemen and volunteers continue to work through the mountain of mangled concrete and steel for a third day after staying on the job for a second straight night. 

Amid frustration about the slow pace of the efforts, thousands of anxious relatives stormed the site prompting police to fire tear gas to disperse the crowd, and leaving 50 injured. 

'We want to go inside the building and find our people now. They will die if we don't find them soon,' said Shahinur Rahman, whose mother is missing at the site where workers made cheap clothes for Primark.

Escape: Rescuers used massive strips of cloth as escape chutes from the textile factories to help the workers escape the devastation after the eight-storey building collapsed in Bangladesh
