WASHINGTON - The US has imposed sanctions on six people, including Eritrea’s spy chief and a senior military officer, for allegedly aiding Somali militants. A Muslim cleric in Kenya and a Sudanese man are also accused of providing financial and logistical support to the al-Shabab group. Two other Kenyans named by the US Treasury Department are in jail. Eritrea is already subject to UN sanctions for supporting the Qaeda aligned militants, which it denies. Al-Shabab, which joined Qaeda earlier this year, is fighting UN-backed government in Somalia.
