Yemeni official media accused Houthis of violating a newly-signed peace deal brokered by Qatar, saying that a newly-signed peace deal are unlikely to succeed in the current environment and will only result in further suffering as Shiite rebels deployed affiliates on several points along the main highways linking Harf Suian to Sa'ada.

Houthis recently have beefed up armed presence in Harf Sufian district of Amran province, south of the troubled province of Sa'ada, pro-government media reported, adding that the rebels have seriously breached the six-point truce agreement that they signed with the government on February 11.

Observers said that once Houthi affiliates were for peace they would carry their babes and live peaceful life instead of carrying automatic rifles. "Holding tightly to their rocket-propelled grenade launcher near their detachment, Houthis are not for peace," they said.

"The fragile truce deal allowed the rebels to regain their strength after they completely tightened their grip on Sa'ada province and slowly advanced in areas out side," they added.

Yemeni government repeatedly accused Houthis of waging secret assassinations against tribal leaders who are loyal to the government and took parts in the previous government-led war against the rebels.

In 2008 the government and Houthis signed a cease-fire deal mediated by Qatar in Al-Doha, capital of Qatar and on Feb 11, 2010, the government and the rebels struck another cease-fire agreement, but both sides were still trading accusations against each other over breaching the truce.
