Nightly fireworks and loud explosions have kept many residents awake until early morning hours around the country.

Residents have taken to Twitter.com to complain about the nightly fireworks displays that continue nightly since May.

"It's always like 9, 10 p.m., and at first we didn't know what it was," said Marquita Spraggans. Many thought the loud sounds were protesters blowing up ATM machines.
