By Saeed Shah, Idrees Ali ISLAMABAD/WASHINGTON (Reuters) -A top Chinese-made Pakistani fighter plane shot down at least two Indian military aircraft on Wednesday, two U.S. officials told Reuters, marking a major milestone for Beijing's advanced fighter jet.

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

Pakistan said Chinese fighter jets were used to respond to military strikes by India and that it has kept Beijing fully informed of its action as tensions in the disputed Kashmir region escalate.
