I don't think he can do that. Landlord's can't evict people or refuse to renew the lease until 2010 february.
go down to the baladiya office that has been set up to deal with tenant issues versus landlord. Take your lease and the recent letter from the landlord. also take proof of last increase as he may also not be eligable to increase again as per the law... (Depends on last increase and the clauses in your lease)
