Iranians and observers describe what they say is a continued crackdown in Iran.

LONDON -- Even as a fragile two-week ceasefire between Iran and the U.S. holds– sparing about 90 million Iranians from the immediate threat of bombardment–many Iranians at home and abroad say they still face an intensifying wave of threats from the Islamic Republic regimeas it continuescrackingdown on dissent.

The leaders of the Iranian regime have escalated measures to silence any kind of protests and criticisms against their policies both inside the country and across its diaspora, Iranians and observers inside the country and abroad told ABC News.

Shiva, a London-based Iranian journalist, says she has received direct threats from Iranian security forces, been labelled a “traitor”and had her assets in Iran confiscated.Shiva and other Iranians who spoke with ABC News in recent daysasked not to be identified bytheirreal names because of security concerns.

She is one of more than 400 Iranian journalists and artists abroad whose assets in Iran have been seized by the Islamic Republic for allegedly supporting what authorities describe as "hostile foreign actors," according to a judiciary statement issued on April 11.

Since the beginning of the U.S.-Israeli war on Iran, the Islamic Republic judicial authorities have repeatedly said that they would adopt extreme measures against those who “collaborate with the enemy”–a broad accusation that they usually use against protesters.

The measures range from harsh sentences by the judiciary including death sentence and lengthy prison terms on protesters at home, to seizing local assets belonging to dissidents abroad.

Despite the threats against her, Shiva says she is most concerned about her family who live in Iran and could face harassment by authorities because of her reporting, she told ABC News on Wednesday.

Having covered the situation of human rights violations in Iran, she added that she is "extremely worried" about the situation of the imprisoned protesters in the country.

"What worries me is my family, and the people inside Iran," Shiva said, "the voices of people inside the country are not being heard – those who are at risk of execution, those who are being silenced."
