A top State Department official called on the Iranian government to remove blocks on social media sites on Tuesday as Iranians continue protesting the regime in cities and towns across Iran.

Undersecretary of State Steve Goldstein said Instagram and other major social media platforms are "legitimate avenues for communication" and called on the Iranian government to unblock those sites so protesters could reach each other and share their message, the Associated Press reported.

President Trump and other senior administration officials have voiced support for the uprisings against the Iranian regime and have warned the government there that the U.S. and other Western nations are watching closely for human rights abuses against demonstrators. More than 20 people have died during several days of unrest in Iran.

Trump has lashed out at his predecessor for not doing enough to curb the "corrupt Iranian regime" at the heart of the protests. The president began focusing on the disconnect between the Iranian people and their theocratic government during his speech to the United Nations General Assembly in September.

The protests in Iran have raged for six days. The demonstrations have taken place in the streets of major cities and rural towns alike, suggesting widespread dissatisfaction with the government.
