Cairo: The Yemen summer has seethed with pitched battles and bloodshed, raising fears that the country will tumble into further disarray even as Washington has more than doubled its military and security aid.
Gun fights and explosions break out in spasms across a nation at the dangerous intersection of the Middle East and the Horn of Africa.
In the south, an Al Qaida-linked network has carried out strategic attacks on security targets, while in the north, a rebel group has renewed fighting against rival tribes and government forces.
The country is accustomed to extremism and tribal animosities, but the fighting is an indication that President Ali Abdullah Saleh remains unable to outflank his enemies, despite increased raids on Al Qaida militants and a restive truce with the northern insurgent group, known as the Al Houthis.
Desperation and anger are feeding militant organizations such as Al Qaida in the Arabian Peninsula, which has also set its sights on international targets. It claimed responsibility for the failed bombing of a US passenger jet in December and the attempted assassination of a Saudi prince.
Security assistance
Washington has increased its security assistance to Yemen from $67 million (Dh246 million) to $150 million and is training and providing intelligence to the country's special forces.
The Al Qaida faction responded with an assassination attempt against the British ambassador in April, a string of deadly attacks on security forces that began in June and is apparently behind the launch of an English-language magazine, Inspire, aimed at broadening recruitment with articles on making bombs and using encrypted messages.
Al Qaida's assaults in the south have been bold and coordinated, including simultaneous attacks on two police stations in Zinjibar on July 14 that killed at least three officers and a June raid on a security headquarters in Aden, freeing prisoners and killing 11 people.
They come as American-born cleric Anwar Al Awlaki, whom the Obama administration is seeking to assassinate, is becoming more prominent in the militant group.
The recent attacks suggest Al Qaida is manipulating its tribal connections to exploit tensions in a widening and violent southern secessionist movement. Filled with angry and unemployed young men, the south is rich territory for recruitment and inciting clans against the state.
"Al Qaida wants to seduce the tribal people onto their side," said Saeed Ali Jemhi, an expert on the group.
"Young people have a high readiness. They are very religious. They hate foreigners, especially Americans. So, Al Qaida comes to them and it's easy to convince them."
Pressing threat
The southern secessionist movement, which many officials regard as the most pressing threat to the nation's stability, does not appear to share an ideology with or have significant ties to Al Qaida in the Arabian Peninsula.
Some analysts suggest, however, that the chaos orchestrated by both groups plays into a government's strategy to portray them as twin dangers sharing the same objective.
"Every Al Qaida attack in the south comes with great relief for the government and more pain for those who call for separation," Hakim Almasmari, editor of the Yemen Post, wrote this week in a column headlined "Government Hoping for more Al Qaida Attacks in South."
"The government gains even more financial support from the international community as it is funding Yemen's fight against extremism."
In the north, a truce in February with the Al Houthi rebels ended six years of intermittent fighting that had left hundreds dead and more than 300,000 displaced. But in recent weeks, clashes between the rebels and clans loyal to the government have killed dozens of people.
On Monday, tribal leaders say the Yemeni army was drawn into the conflict when insurgents captured scores of soldiers and seized a military base in fighting that left at least 10 dead.
Amid defence ministry denials that a large number of troops had been captured, tribal sources and unconfirmed media reports on Thursday said the rebels had freed as many as 200 soldiers.
The Al Houthis have long complained of discrimination and sparse economic opportunities. Their war with the government went international last year when Saudi Arabia bombed Al Houthi positions for months following cross-border incursions by the rebels.
