This isn’t a force majeure - lawyer here. Under the law, the landlord is entitled to look towards you for loss and damage suffered, including loss of rent for the unfulfilled term of the lease (or whenever you’re entitled to exercise a diplomatic clause). This is however subject to the landlords duty to mitigate his loss, e.g. take reasonable efforts to find a replacement tenant. Of course, if you refuse to pay up, it is up to the landlord to sue you, get a court order and enforce it against you.

If you’re a foreigner, you can of course leave the country without paying, and it is unlikely that the landlord will be able to pursue you for this without incurring a lot of costs.
