The United States has said it stands with India and strongly condemns all acts of terrorism, calling for perpetrators of the "heinous" Pahalgam terror attack to be brought to justice.

Days after the brutal killing of at least 26 people, including tourists, in Pahalgam in the Kashmir Valley, several parts of India witnessed candle marches and protests to mourn the deaths of those killed and to express anger at the terrorist attack.

Twenty-six men were killed and 17 were injured when suspected militants opened fire at tourists in India's Jammu and Kashmir territory, police said.
