Interesting. I'm no military Mortar expert. But it seems the Mavic would indeed be limited to some home-made version. Research I could find shows the Mavic 3 can lift and carry about 764 gram (1.68 lbs) and that standard military mortars weigh about 1.43kg-1.8kg (3.15 lb-4.1lb). Wouldn't surprise me if they made mistake on the name. The Matrice, and others would certainly be more than capable. Some of them capable of multiple even.

I went by the news claim on the first link, the second one I don't think specifies what model of drone it was. To your point, I thought the explosion on the first one looked a little lame for a military mortar, but I'm no expert. They sure both have zoom cams that at least look like the Mavic3 though.
