ISLAMABAD, Jan 9 (Reuters): Pakistan is in the final phases of striking a $1.5-billion deal to supply weapons and jets to Sudan, a former top air force official and three sources said, promising a major boost for Sudan's army, battling the paramilitary Rapid Support Forces.

Their conflict has stoked the world's worst humanitarian crisis for more than 2-1/2 years, drawing in myriad foreign interests, and threatening to fragment the strategic Red Sea country, a major gold producer.

The deal with Pakistan encompasses 10 Karakoram-8 light attack aircraft, more than 200 drones for scouting and kamikaze attacks, and advanced air defence systems, said two of the three sources with knowledge of the matter, who all sought anonymity.

It was a "done deal", said Aamir Masood, a retired Pakistani air marshal who continues to be briefed on air force matters.

Besides the Karakoram-8 jets, it includes Super Mushshak training aircraft, and perhaps some coveted JF-17 fighters developed jointly with China and produced in Pakistan, he added, without giving figures or a delivery schedule.

Pakistan's military and its defence ministry did not immediately respond to requests for comment.

A spokesman for Sudan’s army did not immediately respond to a message requesting comment.

Assistance from Pakistan, especially drones and jets, could help Sudan's army regain the air supremacy it had towards the start of its war with the RSF, which has increasingly used drones to gain territory, eroding the army's position.

Sudan's army accuses the RSF of being supplied by the United Arab Emirates, which has denied supplying weapons.
