附属分支

satellite extension

据澳大利亚报纸《The Age》报道，周一(1月11日)，四个位于菲律宾南部的恐怖组织联合宣布成为伊斯兰国的附属分支。专家认为，这一事件预示着伊斯兰国在更广泛的地区寻求更大的影响力。这一分支组织建立在棉兰老岛，该岛也是菲律宾最混乱的地区之一，穆斯林武装和政府展开旷日持久的游击战。

Four Islamic terror groups in the southern Philippines have jointly formed a satellite extension of the Islamic State (IS), Australia’s The Age newspaper reported on Monday. This indicates that the Islamic Sate is seeking influence in more regions, experts say. The branch is based on Mindanao Island, the most lawless part of the Philippines, where Muslim guerrillas have waged a continuous war against the government.

Satellite在这里指的是“卫星国、附属组织”。Extension可理解为“扩展、分支”，相当于branch。
