حذرت السفارة الأميركية في صنعاء من هجوم إرهابي خلال الأيام المقبلة Yemen: US embassy warns of terror attacks Sanaa, 10 August (AKI) - The US embassy in Yemen has warned American citizens of possible attacks in the country in the coming days. The embassy in a statement urged US citizens to avoid crowded areas, not to travel outside of the capital Sanaa and to vary their travel routes and times travelling to and from work. According to a report by the Arab newspaper, al-Hayat, the authorities in Yemen have taken "exceptional" security measures close to government buildings, embassies and foreign companies which are considered to potential terrorist targets. On Wednesday, the Yemen military killed four alleged terrorists in a raid against a suspected al-Qaeda hideout in Mareb. On Thursday militants attacked a government building and a power plant in the northern Yemeni province. An official in Mareb said that al-Qaeda was not behind the attack on the power plant and that it had been carried out by a tribal group avenging the killing of fellow tribesmen by security forces. Arif al-Zuka, a representative of the Mareb province told al-Hayat newspaper that "some relatives of the two terrorist killed on Wednesday opened fire from far away, on a post, killing a citizen that was found in the area." The authorities had initially thought that al-Qaeda was behind Thursday 's attack.
