(CNN)The US is looking into reports that Pakistan misused American-made F-16 jets during an aerial engagement with India last week that brought the two nuclear armed neighbors to the brink of conflict.
US looking into reports Pakistan violated arms agreement in Kashmir
Both India and Pakistan launched airstrikes over the Line of Control -- the de facto border that separates the two countries in disputed Kashmir -- in the first such incursion since 1971. An Indian jet was shot down in the dogfight and its pilot held in Pakistan custody for several days before Islamabad released him back to New Delhi on Friday.
Pakistan has stated that no F-16s were used in the operation, though it hasn't specified what military equipment was involved.
