A BBC Arabic analyst in a short article, that starts with:
An offshoot of al-Qaeda in the Arabian Peninsula (AQAP) has issued a statement threatening the lives of 73 Yemeni soldiers it says it captured last week.
Then adds:
Ansar al-Sharia, whose name means "Partisans of Islamic law" in Arabic, was formed by AQAP in response to the growing youth movement in Yemen..
Ends with:
Many of those involved in Ansar al-Sharia are jihadists who have experienced living in an "Islamic state", either in Afghanistan in the mid-1990s, or among jihadists in Iraq after the US-led invasion in 2003.

Ansar al-Sharia's ability to launch attacks, as well as build local support, indicates that the Yemeni authorities' struggle with Islamist militants may soon become bloodier and more protracted.
