Yemen: More U.S. troops being sent.

    There have been some U.S. Special Forces in Yemen for some time. Indeed a  group was attacked in Aden. However training of Yemeni forces was suspended during the time when there were negotiations for Saleh to step down. Now the U.S. supported president Hadi is in power military aid has resumed and now troops are being sent as well.
     The troops will cooperate with Yemeni security forces in counter terrorism operations. No doubt we will see renewed attempts to retake territory captured by militants in southern Yemen. Any militant Islamis group now seems to be described as Al Qaeda or linked to that group. AQAP is the official Al Qaeda group in Yemen.
     The new U.S. troops will work under secret arrangements. At the same time drone attacks are being increased. Targets have also been broadened with signature strikes based upon behavior now being allowed. Targets now need not be specifically identified. This broadening will no doubt increase the number of civilians casualties. For more see this article.

Yemen: Al Qaeda surveillance reports U.S. troops in Aden

An Al Qaeda group claimed that it had attacked a U.S. intelligence officer after their surveillance showed increasing numbers of U.S. troops in the city of Aden. The new leader Prime Minister Hadi a vice-president under Saleh has vowed to continue the fight against Al Qaeda and other militant groups. He is supported by the U.S. even though he was the sole candidate for president and Saleh supporters and relatives still are the major group running the government.
The statement about the attack came from an AQAP (Al Qaeda in the Arabian Peninsula) website. The Pentagon has confirmed the attack but claims no one was killed. The website said of the intelligence officer:"He was targeted after increasing U.S. activity in Yemen in the light of new political circumstances, and the bringing of a large number of U.S. soldiers to Aden in particular," The site also urged a jihad against the Crusader enemy and to fight the American occupiers of Yemen.
A related militant group Ansar al-Sharia has claimed responsibility for a number of attacks that have killed so far at least 110 Yemeni soldiers in the south of Yemen.
The campaign of assassinations by U.S. drone strikes has been followed by increased militant activity involving taking over the entire province of Abyan at one point. There is also an active separatist movement in the south of the country. At one time the south was a separate country. For more see this article.
