Around 1,000 Qatari military forces have reportedly joined the Saudi troops in their operation in Yemen.
Al-Jazeera news channel reported on Monday that the troops entered Yemen through Saudi Arabia’s al-Wadiah border crossing.
The report said that Qatari forces were backed by more than 200 armored vehicles and 30 Apache combat helicopters.
According to the report, with the deployment of the Qatari troops in Yemen, the number of Persian Gulf Arab countries’ forces in the war-hit country will increase to 10,000.
Reports also indicate that Saudi Arabia has deployed a further 1,000 Special Forces to fight Houthi militants.
Dozens of Saudi tanks and armored vehicles have reportedly arrived in Yemen over the past 48 hours from Wadia crossing, a border checkpoint in the south of the kingdom.
Earlier this week, 2,800 Saudi Special Forces along with intelligence and logistics officers entered Yemen.
Media close to Yemen's fugitive former president Abd Rabbuh Mansur Hadi also claim that Morocco, Jordan, Kuwait and Egypt are set to dispatch troops to the Yemeni provinces of Aden, Tai’zz, Ma’rib and Hudaydah.
The conflict has so far left about 4,500 people dead and thousands of others wounded, the UN says. Local Yemeni sources, however, say the fatality figure is much higher.
