The Military Committee formed under the GCC-crafted power transfer deal has approved using of helicopters in the hunt of saboteurs.
The committee reversed two helicopters to pursue those who blockade main roads linking between major cities, the state news agency, Saba, said.
The committee ordered to set up security checkpoints in the main road linking between the port city of Hodeida and the capital Sana'a as well as checkpoints in the Sana'a-Marib road.
Road blockades and attacking oil, gas pipelines, and electricity plants by tribesmen caused many problems to the interm government and people.
According to Saba, more than 130 road blockades occurred in different Yemeni governorates in October, pointing out that attempts of security forces to remove such blockades led to the killing of eight persons and wounding more others. Some tribes try to put pressures on the government through blockading roads, particularly after the eruption of Yemen's uprising in 2011.
Killings and other criminal acts have remarkably increased in some governorates due to revenge and armed disputes as armed men exploited insecurity in Sana'a to carry out killings and tribal revenge.
Major cities witnessed a state of loose security following the ouster of the former president Ali Abdullah Saleh who some of his relatives still run military services.
The Interior Ministry has declared a ban on weapons carrying inside cities, but armed men are still seen roaming with AK-47 assault rifles, hunting rifles and pistols inside Sana'a streets.
