TEHRAN (FNA)- Riyadh has transferred nearly 5,000 militants from a number of terrorist groups from Aden port to Eritrea's Assab port to go under military trainings and then be sent to the Saudi provinces bordering Yemen, sources said.

"The terrorists, some of whom are from the Al-Qaeda, will be dispatched to Najran, Jizzan and Asir provinces to fight against the Yemeni army and popular forces and prevent their further advances in Southern Saudi Arabia," the sources stated on Sunday.

They added that the Yemeni forces' advances deep inside the Saudi territories have frightened the Saudi officials more than the ballistic missiles fired from Yemen.

Also, Hossein al-Houthi, a commander of the Yemeni popular forces, told FNA that his forces have managed to retake control of several villages from the Saudi mercenaries and destroyed five of their tanks, their military outposts and a command room of the Saudi-led coalition in Ta'iz province.

Reports said on Friday that Yemen's long-range home-made missile dubbed as Borkan-1 (Volcano-1) hit deep inside Saudi Arabia in response to the kingdom's massacre of civilians in the impoverished nation.

Borkan-1 has a range of 800 kilometers and is a new generation of Yemen's domestically-made missiles, Yemen's Defense Ministry announced in a statement.

The Yemeni defense ministry did not mention the exact location of the targets that Borkan-1 missile has hit.

It, however, said that the warhead of Barkan-1 missile has been designed to destroy the Saudi military base structure with respect to the materials used in their construction.

On Wednesday, the Yemeni army and popular forces hit the Saudi military positions in the kingdom's Najran province with a Zalzal-3 ballistic missile in retaliation for the Saudi airstrikes on residential areas across Yemen.

The Yemeni missile attack inflicted heavy losses on the Saudi troops in Najran province.

Early reports indicated large casualties on the Saudi forces in the missile attack. The Saudi army and its coalition members have lost, at least, over a hundred troops each time they have come under a ballistic missile attack by Yemen.

The Saudi-led forces' armored vehicles were destroyed during the Yemeni missile attack.
