From CNA:
The Vatican City State has toughened sanctions for those who try to illegally enter its territory in areas where free access is not allowed.
In a decree issued last month by the Holy See, the monetary sanctions and prison sentences for those who violate the strict security regulations of Vatican City have been considerably increased. The document, signed by Cardinal Fernando Vérguez Alzaga, president of the Pontifical Commission for Vatican City State, provides for monetary fines ranging from 10,000 to 25,000 euros (about $10,200 to $25,700) and prison sentences ranging from one to four years.
