"Ahrar al-Najran forces arrested a UAE officer and several Saudi militaries by attacking Al-Huriya Police Center in Najran on Tuesday," Abu Masoud, a senior leader of Ahrar al-Najran, told Al-Alam News Network on Wednesday.

Abu Masoud noted that Ahrar al-Najran fighters, backed by al-Shabab movement of Najran, also won full control of the city of al-Akhdoud in the Southern parts of Najran near the Yemeni border after inflicting heavy casualties on the Saudi forces.

Ahrar al-Najran declared existence in June. Tribal forces and activists in Saudi Arabia's Najran region formed an armed opposition movement to the Saudi regime, called "Ahrar al-Najran", after the region declared separation from Saudi Arabia and joined Yemen in the war on Riyadh.

Activist and movement member, Abu Bakr Abi Ahmad al-Salami, told Al-Alam News Network that in June "all tribes of the region are members of the Ahrar al-Najran Movement".

He said the youths and political activists in Najran have demanded the "Yemeni popular forces and revolutionary committees, brothers, and the neighboring lands to provide military training for the younger generation of this region".

Al-Salami underlined the movement tough stance against the al-Saud regime, saying, "Saudi Arabia wrongfully imagines that it is the only defender of Islam, but they should know that we are the defenders of Islam and the two holy mosques, and we will rush to defend the two mosques (in Mecca and Medina) if necessary."

Al-Salami said the movement is worried about developments in Yemen, and declared that "the movement's first battle will take place in those areas controlled by the Saudi occupation army in Southern Najran soon".
