Indian police said "leftover explosives" were responsible for a blast in Kashmir that killed at least five civilians Sunday as they protested against government forces shooting dead three alleged militants.
Protesters had surged the site of a shootout in southern Kulgam town, chanting slogans against Indian rule and hurling rocks at troops as they fired at unidentified gunmen.
Three alleged rebels were shot dead in the exchange but a subsequent explosion at the scene killed five demonstrators, said inspector-general of police Swayam Prakash Pani.
"Protestors ignored warnings and soon overwhelmed the site, where five died after being hit when leftover explosives went off," he told AFP.
At least 30 other civilians were wounded in clashes with police, another officer and witnesses at the scene said.
Mobile telephone services were suspended in the area as protests spread.
