The first investigating judge in Beirut issued the arrest warrant on the basis of a lawsuit filed by lawyer Ashraf al-Moussawi and a group of lawyers for allegedly slandering, insulting and inciting Hezbollah Secretary-General Hassan Nasrallah.
The prosecution accuses Maalouf of inciting "Israel to assassinate Hezbollah leader Sayyed Hassan Nasrallah through acts and writings and inciting sectarian strife, and therefore decides to try her in the Beirut Criminal Court and include the charges and expenses and deposit the papers with the appellate public prosecutor in Beirut, .
In March 2016, Maria Maalouf chanted: "If Israel really wants peace, prove it, and make treaties with Hezbollah, until today we have not been rid of Hassan Nasrallah, who is waging war against us."
After the fierce campaign against her by the Hezbollah media at the time, Maalouf said: "It is not surprising to those who harassed the purest women of the land Aisha, may Allah be pleased with her to harass Maria Maalouf in Lebanon; because it stands against the terrorist Hezbollah and Iran!"
And then confirmed that it will move a case against Hassan Nasrallah, "for war crimes and threats to civil peace in Lebanon and a number of Arab countries."
