This has a ghostly resemblance to the AA crash on approach to Cali.. Out here in Afghanland due to a number of issues it's not uncommon to find oneself in an area of mountainous terrain and being vectored into IMC conditions below the MSA.. the natural reaction should always be.. "whatever else we do let's climb".. after all the crew didn't plan to be off-airways or below a safe MSA in IMC away from their selected route.. If you can't get visual, Get Safe. ..
