Soccer fans in Iran's Kurdish region set off fireworks and honked car horns early Wednesday to celebrate the U.S. win over the Iranian national team in a politically charged World Cup match that divided the protest-riven country.

Cheering fans hit the streets in Iran's Kurdish-majority province of Kurdistan and fireworks lit the skies over the Bukan area of West Azerbaijan province to celebrate the Iranian team's 1-0 loss.

Some shouted "Death to the dictator," a popular protest slogan referring to the Iran's Supreme Leader Ayatollah Ali Khamenei.

The Kurdish areas of Iran have been hot spots of ongoing anti-government demonstrations.

Woman whose death set off protests was Kurdish

The protests first erupted in September, following the death of a young Kurdish woman in the custody of Iran's morality police in the capital, Tehran.

The protests quickly morphed into the most serious challenge to Iran's theocracy since its establishment in the 1979 Islamic Revolution. Iranian authorities have blamed foreign actors, chiefly the U.S., for orchestrating the protest movement, but have provided no evidence.

Iran's Kurdish-majority areas have seen waves of unrest amid nationwide protests against the government. The national team's loss to the United States was seen by some as a victory against what they see as oppression by the government.
