President Donald Trump is again cheering on the protesters in Iran, saying: "The people are finally getting wise as to how their money and wealth is being stolen and squandered on terrorism."

Trump tweeted Sunday that it looks like the Iranians "will not take it any longer." And he adds: "The USA is watching very closely for human rights violations!"

Trump's tweets the previous day angered Iran's government, leading the Foreign Ministry spokesman to say the "Iranian people give no credit to the deceitful and opportunist remarks of US officials or Mr. Trump."

A wave of economic protests is sweeping major cities in Iran. The first deaths occurred overnight when two protesters were killed during clashes at a rally in Doroud

The CEO of Telegram says Iran is "blocking access ... for the majority of Iranians" after protesters used the popular messaging app to plan and publicize demonstrations.

CEO Pavel Durov made the announcement on Twitter Sunday.

Iranians said the app is now inaccessible by mobile phone networks.

The Telegram app has been used to share videos of the protests, the largest since 2009, and times for new rallies.

Users said Sunday that they could no longer access the app via cellphone networks, though it was still available via Wifi and home internet connections.

Iranian media also reported the disruption.

The Iranian government did not immediately comment.

A semi-official news agency in Iran has quoted a government official as saying two protesters were killed at a rally overnight.

The Mehr news agency reported Sunday that the two protesters were killed in Doroud, in Iran's Lorestan province.

Mehr quoted Habibollah Khojastepour, the security deputy of Lorestan's governor, as saying an illegal gathering in Doroud took place on Saturday night and ignited clashes.

He said "two of our dear Doroudi citizens were killed," without elaborating on the cause of death.

Protests in Iran began Thursday in Mashhad over economic issues. The protests have expanded to cities across the Islamic Republic in the days since.

Dozens have been arrested since the protests began.
