Yemen's defense ministry has formed a panel to investigate the bombing that occurred s at the headquarters of the first armored division in the capital Sanaa early on Thursday, the state news agency Saba reported.
The panel will be headed by Muhammad Ali Al-Maqdashi, deputy chief of staff for technical affairs, it said.
Several bombings shook the HQ of the first armored division, which defected to the popular uprising in early 2011.
Preliminary reports suggested the bombings were as a result of a fire inside a weapons store that included missiles and tank rockets during a training by soldiers from the division.
The division controlled the bombings in almost an hour.
Sources at the division said soldiers on training hit tires that caught fire and led to the explosions inside the weapons store.
No casualties were reported.
The development comes as the new Yemeni government is working hard to restructure the armed forces that divided during the popular uprising in 2011.
The army divided into pro- and anti-revolution forces led by Ali Muhsen, commander of the first armored division and who was once a close aide to the former president, and Ahmed Saleh, the elder son of the former president and commander of the first elite forces, the republican guard.
The restructuring comes under a power-transfer deal which was brokered by the GCC countries and backed by the West after the turmoil.
Meanwhile, calls are growing to accelerate the restructuring to pave the way for a comprehensive dialogue conference planned to be held in mid-November.
