JAKARTA: The ease with which three separate groups of ethnic Uighur militants sneaked into Indonesia is ringing alarm bells for security forces, who are on high alert for a far deadlier attack than last week's assault on Jakarta.
At least 10 Uighurs, who hail from China, arrived in the world's most populous Muslim nation over the last 18 months to join radicals, exposing an extensive support network ready to welcome wannabe militants.
