"People against the regime are outside Syria," he said. "War always has its reasons and its logic, and the true reasons for it are always hidden."
Fr. Haddad also criticized the war.
"The Syrian war is not a crisis between Muslims and Christians or Muslims and other Muslims and it's not a Syrian civil war from and for Syrians," he told CNA.
"This is a war imported from outside and we have traitors who have sold themselves to outsiders for a bit of money."
He said that the rebels are "trying to show there is a problem between Christians and Muslims in Syria when there isn't and there never has been."
During his homily he called the kidnappers "traitors" and said Syrians need to solve their own issues "like in a conclave, without outside intervention."
"Our petro-dollar Arabic neighbors have bought some Syrians and it's a surprise to me when a Syrian is happy to see a Syrian soldier murdered," said Fr. Haddad at the basilica.
He added that now there are "terrorists and non-terrorists from Libya, Pakistan and Afghanistan who have gone to fight in Syria saying they want to liberate Jerusalem."
"But can one liberate Jerusalem from Aleppo?" he asked. "We all know where the path to Jerusalem is."
