A Chinese-made Pakistani fighter plane shot down at least two Indian military aircraft on Wednesday, two U.S. officials told Reuters, marking a potential major milestone for Beijing's advanced fighter jet.

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.

The strikes targeted at least nine sites “where terrorist attacks against India have been planned,” India’s Defense Ministry said.
