ISLAMABAD — Pakistan said Friday that this week’s armed clash with India set back the peace process between the two nuclear-armed rivals and warned New Delhi to refrain from any ‘‘adventure,’’ saying the army would respond to aggression.
Exchanges of fire are common along the tense and heavily guarded frontier, but this week’s flare-up, which left more than 20 people dead, is the most serious violation yet of a 2003 cease-fire agreement.
‘‘We say yes to peace, but we will not accept hegemony of any country,’’ Interior Minister Chaudhry Nisar Khan said after attending a meeting convened by Prime Minister Nawaz Sharif to discuss tensions along the Line of Control that separates Pakistan-controlled Kashmir from Indian-held Kashmir.
Khan said the National Security Committee decided to write a letter to the United Nations about the ‘‘unprovoked Indian firing,’’ which began on Sunday as Muslims in the region were preparing to celebrate the Eid al-Adha holiday.
