This is a major escalation that could greatly expand the war and drag hezbollah deeper into the war, which was already involved in skirmishes with Israel in Lebanese regions that Israel occupies.
Note: the verbiage of the article is minimizing the focus on Israel, and they spend half the article justifying the attack as “not an attack on Israel” an effort to minimize how much of an escalation this is.
One last comment, pointing out biases in Reuters does not mean I ignore them. Every source is biased one way or another, and I still read them (refer to the very post you’re commenting on), albeit with skepticism, carefully scanning for the facts and evidence.
