Nationwide student protests started this month. On February 12, the demonstrations attracted global attention when three people were killed.
Demonstrators are demanding better security, an end to goods shortages and protected freedom of speech.
Major social and economic problems have fueled the protests. But as the demonstrations gained steam, officials have pointed fingers at other factors and accused the United States of plotting to destabilize the government.
Some blame Venezuela's government, led by President Nicolas Maduro, for those problems. Maduro and other officials blame the opposition for the security and economic problems.
The protests are the largest Maduro has faced in his 11 months in power. He has called opposition members fascists and compared them to an infection that needs to be cured.
Many demonstrators across the country are students. Prominent opposition politicians have also led protests and joined marches.
Since February 13, more than 2,000 stories from Venezuela have been uploaded to iReport, CNN's user-generated platform. Many of the videos and photos are gruesome and depict violent scenes between demonstrators and police.
