A surprise victory by Pakistani Chinese-made jet fighters in an air battle with Western-made Indian aircraft has triggered alarm in the global defense industry. The opening of hostilities on Wednesday morning between India and Pakistan saw one of the largest air battles in modern history,

Delhi has not acknowledged the loss of any of its planes and instead said it carried out successful strikes against what it said was "terrorist" infrastructure inside Pakistan.

Pakistan says it shot down five Indian fighter jets, which it identified as French- and Russian-origin fighter aircraft.
