Pakistani officials have accused Indian troops of killing two civilians after firing across the border in its eastern province of Punjab.
The officials said the latest incident occurred in the Sialkot region, which faces the southern part of India's autonomous Jammu and Kashmir state.
Indian paramilitary official Dharmendra Pareek said Indian forces returned fire after Pakistani forces fired guns and mortar shells on Indian border posts and at least three villages.
He said one Indian border guard and three civilians were injured.
Last month, Indian police accused the Pakistani Army of killing a soldier and wounding seven other people during firing along the border in the same region.
India and Pakistan often accuse each other of violating a 2003 cease-fire agreement in Jammu and Kashmir.
The two countries have fought three wars, two of them over the disputed Kashmir region.
