Hundreds of members of India's Sikh community took to the streets on Tuesday to protest the killing of 19 people, mostly Afghan Sikhs and Hindus, by a suicide bomber in Afghanistan.

Brandishing black flags and chanting Sikh prayers, they marched near the Afghanistan Embassy in New Delhi to seek better protection of the Sikh community living in Afghanistan.

The Islamic State group on Monday claimed responsibility for the suicide bombing.

The bomber targeted a delegation from the minority communities as it was travelling to the governor's residence in the eastern city of Jalalabad on Sunday for a meeting with President Ashraf Ghani.

Avtar Singh Khalsa, a longtime leader of the Sikh community, was among those killed.

Another 20 people were wounded.
