"P has denied that the surgical strikes took place on Thursday and have called it cross border firing."
This is an extract from a News paper. I think after "Thursday and" there should be "Has" instead of "Have". Am I correct?
Yes, except for the capitalization. It should say "has" instead of "have".
I am not a teacher.
I'd use cross-border.
So would I. I missed that.
