Sana'a manuscript: The Sana'a palimpsest, dubbed Ṣanʿā’ 1, is one of the oldest Quranic manuscripts in existence.  Part of a sizable cache Quranic and non-Quranic fragments discovered in Yemen during a 1972 restoration of the Great Mosque of Sana'a, the manuscript was identified as a palimpsest Quran in 1981.  It is written on parchment, and comprises two layers of text (see palimpsest).  The upper text largely conforms to the standard 'Uthmanic Quran, whereas the lower text contains many variants to the standard text.  A partial reconstruction of the lower text was published in 2012, and a further reconstruction on different principles was published in 2016.  A radiocarbon analysis has dated the parchment to before 671 AD with a 99% accuracy.

South Yemen insurgency: The South Yemen insurgency is a term used by the Yemeni government to describe the protests and attacks on government forces in southern Yemen, ongoing since 27 April 2009, on South Yemen's independence day.  Although the violence has been blamed on elements within the southern secessionist movement, leaders of the group maintain that their aims of independence are to be achieved through peaceful means, and claim that attacks are from ordinary citizens in response to the government's provocative actions.  The insurgency comes amid the Shia insurgency in the country's north as led by the Houthi communities.  Southern leaders led a brief, unsuccessful secession in 1994 following unification.  Many of them are involved in the present secession movement.  Southern separatist insurgents are active mainly in the area of former South Yemen, but also in Ad Dali' Governorate, which was not a part of the independent southern state.
