The ABC News (US) report starts off with a blatant inaccuracy. Noting that the people killed worked for Al Manar TV and Al Mayadeen, that reporter said that Al Manar was "state channel" in Lebanon while Al Mayadeen has "some kind of link or affiliation with Hezbollah."
In fact, Al Manar is owned by Hezbollah. Its initial webpage (in 2003) said, in English, that its purpose was psychological warfare against the Zionist enemy.
Hezbollah itself has said quite clearly that there is no distinction between its political and military activities. Hassan Nasrallah's successor Naim Qassem has said, "We don't have a military wing and a political one...Every element of Hezbollah, from commanders to members as well as our various capabilities, are in the service of the resistance, and we have nothing but the resistance as a priority." Al Manar's website shows that the station regards its media operations as being military as well.
Al Manar, before it sought respectability as a major Arabic language satellite station, made clear its real purpose was military. Everything else is window dressing.
To be sure, reporters - even for a propaganda outlet - should be presumed to be civilians unless there is specific reason to believe otherwise. ABC Australia certainly doesn't know what intelligence Israel had when it targeted the building. But if they cared, they could have found hints that these journalists were considered Hezbollah first, last and always.
The funerals of the two Al Mayadeen workers show that their caskets were covered with Hezbollah flags.
That sure indicates that they were Hezbollah first, employees of Al Mayadeen second.
Still, to be a legal military target, one has to directly contribute to the military operations. That does not only mean carrying a gun: it includes transporting weapons, being a "spotter" and giving information on troop positions or similar to the enemy, delivering supplies to combatants, helping plan military operations, helping facilitate messages between terror cells, setting up or maintaining communications networks used for military purposes. and even boosting the morale of combatants by broadcasting propaganda to them. In some of these examples, one should still assume civilian status when they are not actively engaging in the activities mentioned, but the calculus may be different when Hezbollah itself considers all its members to be militants.
Also, we don't know if the victims were the ones targeted. There might have been Hezbollah officials or weapons in the building that were the actual targets.
Flatly saying that Israel is targeting journalists is libelous. If ABC Australia cared about the truth, they would have done what I just did, and looked at it from the perspective of international law, not a kneejerk assumption that the IDF is monstrous.
