Right now one is heavily speculatory and based on ongoing and disputed events (ie the fact that Israel and its allies will lie through their teeth, same as Russia did, about their intentions until the last moment); the other was a pretty firm event quite literally being acknowledged by the perpetrator. Not only that, but outright annexation is not definitely the intention of Israel - it may be that they want more territory to engage in 'frozen conflict' style 'diplomacy', the same as Russia did with the Donbass for nearly a decade.

For most news sources, it would be reasonable to speculate that there's a strong pro-Israel bias. AP is generally pretty aggressively anodyne, though. If there's a pro-Israel bias, it's likely not a strong one.
