ISLAMABAD: India and Pakistan exchanged more gunfire across the disputed border in Kashmir on Sunday, Indian border guards said, as a 10-year cease-fire frays over accusations of killings of soldiers deployed on the frontline.
One Indian border guard was wounded after Pakistan Rangers opened fire on a post in Kanachak, some 40 km southwest of Jammu, the winter capital of India’s Jammu and Kashmir state, the Border Security Force said.
“It was an unprovoked firing on an International Border post from the other side. However, we responded with utmost restraint,” a spokesman of the Border Security Force said.
Pakistan, however, accused Indian forces of firing on its border posts in disputed Kashmir and in neighboring Punjab province, where it sparked an “intermittent exchange of fire” between the two sides.
“Indian Border Security Forces resorted to unprovoked firing on Pakistani Rangers posts near Pukhlian, Head Marala area, in Sialkot sector,” a senior military official, told AFP.
“Intermittent exchange of fire continues. No loss reported so far,” added the official on condition of anonymity as he was not authorized to talk to the media.
The official said that after the exchange of fire in Punjab, the Indian troops also fired at the Line of Control (LoC) in the disputed Kashmir region. 
“Indian troops also resorted to unprovoked firing at LoC in Nakial sector near Kotli,” he said.
Tensions along the 740-km Line of Control that divides Kashmir rose on Tuesday when an Indian army patrol was ambushed and five soldiers killed in the Poonch region. New Delhi blamed the attack on the Pakistan army. Islamabad denied involvement.
India has linked the cease-fire violations to attempts by Pakistan to push through militants into its side of Kashmir to revive a decades-old revolt there. Islamabad denies any help and instead has called for talks to resolve the disputes between the neighbors including the long-running row over Kashmir. The fighting is the latest in a spate of recent cross-border skirmishes between the two nuclear-armed neighbors who have fought three wars since independence from the British rule in 1947, two over the Muslim-majority region of Kashmir.
Indian Defense Minister A. K. Antony on Thursday hinted at stronger military action along the LoC after Delhi accused Pakistan’s army of involvement in a deadly overnight ambush on Monday that killed five Indian soldiers.
Pakistani Prime Minister Nawaz Sharif tried to ease tensions with India by urging both sides to work swiftly to shore up a 10-year cease-fire threatened by the recent attacks.
But Pakistani military officials on Thursday made fresh allegations of their own, accusing Indian troops of opening fire and seriously wounding a male civilian in the Tatta Pani sector along the LoC.
The picturesque Himalayan territory of Kashmir is divided between India and Pakistan by the UN-monitored LoC, the de facto border, but is claimed in full by both countries.
A deadly flare-up along the LoC in January brought peace talks to a halt. They had only just resumed after a three-year hiatus sparked by the 2008 attacks in Mumbai that killed 166 people. India blamed Pakistani militants for the attack.
More than a dozen armed rebel groups have been fighting Indian forces since 1989, demanding independence for Kashmir or its merger with Pakistan.
Three people were killed in the violence on Friday and the situation remained tense with a curfew imposed in six out of 10 districts of Jammu, state officials said.
India has deployed tens of thousands of soldiers in Kashmir to put down an armed revolt that began in 1989. In recent years militant violence has ebbed, but there has been little movement on a political settlement of the dispute.
On Sunday, army troops patrolled the streets of the violence-hit districts and the local administration blocked mobile data services to stop the spreading of rumors, it said.
