The Leader made the remarks in a statement tweeted in Urdu, English, and Persian on Thursday in condemnation of the brutal killing of more than 40 Muslims during a four-day span of violence that began in New Delhi on February 23, presstv.com reported.

“The govt. of India should confront extremist Hindus & their parties & stop the massacre of Muslims in order to prevent India’s isolation from the world of Islam,” the tweet went on. The violence saw the Hindu mobsters setting mosques on fire and burning Muslims alive in their homes or dragging them out into the streets and lynching them.

Hundreds more were also injured during the melee.

On Monday, Iranian Foreign Minister Mohammad Javad Zarif wrote a tweet, urging “Indian authorities to ensure the well-being of ALL Indians & not let senseless thuggery prevail,” adding that the “path forward lies in peaceful dialogue and rule of law.”

India summoned the Iranian ambassador to New Delhi afterward to protest the comments. The Indian Foreign Ministry’s spokesman Raveesh Kumar said a “strong protest was lodged against the unwarranted remarks,” which he called “not acceptable.”

The violence came following protests by India’s Muslim minority against the Indian government’s approval of a controversial law last December.

The law offers a path to Indian citizenship for six religious groups from three neighboring countries but specifically excludes Muslims. Critics insist the law is discriminatory and comes in the wake of other severe government measures against the country’s Muslim population such as withdrawal of autonomy for Muslim-majority Jammu and Kashmir province that has intensified discord across India about the future of its 200 million Muslims.

Kumar, however, defended the legislation, saying the government was confident in its legality.

On Tuesday, Iranian people, university students, and seminarists held a protest in front of the Indian Embassy in the capital Tehran to denounce the massacre.

The Iranian demonstrators shouted slogans and held up placards bearing statements in support of the Muslims and condemnation of the slaughter.

Some held up pictures showing the harrowing aftermath of the bloodshed.

The protesters urged international and humanitarian organizations to break their silence on the atrocity, decrying censorship attempts aimed at imposing a media blackout on the violence.

The participants called New Delhi to account for the massacre and asked the Islamic Republic’s diplomatic authorities to contribute to efforts that would prevent such atrocities.
