The vessel is a former USN vessel, Swift by class and disposed of to the private sector in 2013 and now operated UAE company. IRRC it was used earlier in the Yemen conflict to move UAE heavy kit to Aden and presumably was ferrying supplies from Assab, Eritrea to the Yemen.

Wiki has:
The UAE leased Swift was reportedly sunk off the Yemeni coast on the 1st of October, 2016 by an anti-ship missile from the brigade 17 tunnel-bunker network in Dhubab [8], the UAE officials reported that the ship was carrying aid when targeted by the anti-ship missile [9]
