TEHRAN, Iran (AP) — Iran’s foreign ministry has summoned Switzerland's envoy in Tehran for a social media post showing Iranian protest icon Mahsa Amini, local reports said on Sunday.

Months of anti-government protests were sparked by the death of 22-year-old Amini in September, after Iranian morality police detained her for allegedly violating the country’s strict Islamic dress code.

A website affiliated with Iran’s state television called YJC.ir reported that the Swiss ambassador, Nadine Lozano, was summoned after a Twitter account affiliated with the embassy in Tehran published a photo featuring Amini.

The Twitter account linked with the Swiss embassy in Tehran also posted an image of Iran's pre-revolutionary flag before its current theocracy came to power. The post added that the Swiss foreign ministry strongly condemned the recent execution of three Iranian protesters.

Iran announced Friday the executions of Majid Kazemi, Saleh Mirhashemi and Saeed Yaghoubi, without saying how the deaths were carried out. Authorities alleged they have killed a police officer and two members of the paramilitary Basij group in the city of Isfahan in November during the demonstrations.

Iranian authorities have repeatedly accused Western powers of fomenting the unrest, without providing evidence.
