In 48 hours, this Muslim group raised $25,000 for victims of the London attack

A crowdfunding campaign to raise money for the victims of Wednesday's terror attack in London has met its goal in under two days. 

Organizer of the campaign, Muddassar Ahmed was inside Parliament when attacker Khalid Masood drove his car into pedestrians on Westminster Bridge, leaving three dead, and stabbed to death an unarmed police officer outside Parliament.

"I saw all the carnage before me. We were trapped there for about four hours"Ahmed said.

Under the title "Muslims United for London," Ahmed posted the campaign on the crowdfunding site LaunchGood.

The site describes itself as a platform to "support Muslims launching good all across the world by helping them raise funds for their campaigns." 

Within 15 hours, it had hit its initial goal of £10,000 ($12,500), and Ahmed doubled the goal. It reached £20,000, or about $25,000, a day later.
