What is the identity of this abandoned, wrecked Sudan Airways airliner?
It looks to me more like an abandoned plane (that's fallen apart) rather than a crashed/wrecked one. A Sudanese A310 crashed at Khartoum in 2008 - but it caught fire and was destroyed, which clearly hasn't happened here unless someone came and repainted it afterwards.

This list gives ten A300s which have previously been owned by Sudan Airways; TC-OYC is stored at Istanbul (and this doesn't look like Istanbul), ST-ATA is stored location unknown, and ST-ASS was scrapped while last owned by Sudan. Of their A310s, ST-AST, is stored (location unclear); ST-ATN was destroyed by fire after a crash. So that's three A300/310s which might plausibly be lying derelict at a Sudanese airport.

For an alternative count, this thread lists four A300s "stored" at Khartoum, ST-ATA, ST-ATB, ST-ASS &amp; ST-AST; all put up for sale as parts/scrap a few years back but never sold. No pictures but it's clear they're not in a great state.
