A migrant labourer was killed and two others injured in a grenade attack by militants in Jammu and Kashmir's Pulwama district on Thursday, police said.

"Terrorists hurled grenade on outside labourers at Gadoora area of #Pulwama. In this terror incident, one labourer died and two others were injured. Area cordoned off. Further details shall follow," the Kashmir Zone Police tweeted.

Militants had stepped up attacks on non-local labourers earlier this year but there was a halt in such targeted killings for the past nearly two months.
