Do I need to serve the three months notice mentioned in contract if I resign during probation?

Hi,

I just wanna ask if I can resign in 14 days even if the notice period in my contract is 3 months.

I am still under probation period on a limited contract and I have decided to go back to my home country.

With termination, will I still have to pay my employer if they would terminate me?

Can employers refuse to accept these terms with MOHRE that I don't have to pay anything?

Do they have the right to file a case and claim all their rights through the court?

How about the terms and conditions imposed and made in the contract?
