Pakistani troops violated the ceasefire along the Line of Control (LoC) in Gurez sector of Bandipora district of Jammu and Kashmir on Friday, a defence spokesman said.
The Indian Army effectively retaliated.
"Pakistan initiated an unprovoked ceasefire violation along the LoC at Kanzalwan in Gurez sector today morning by firing mortars and other weapons," defence spokesman Colonel Rajesh Kalia said.
There were no reports of any casualties so far.
Meanwhile, Pakistan on Friday summoned a senior diplomat from the Indian High Commission in Islamabad to register its protest over the alleged ceasefire violations by the Indian forces along the Line of Control (LoC).
The Foreign Office in a statement said that Indian forces resorted to "indiscriminate and unprovoked firing" in the Hotspring and Jandrot sectors on Thursday, resulting in serious injuries to 15-year-old Irum Riaz; 26-year-old Nusrat Kausar and 16-year-old Mukheel of Andrala Nar village.
