Syria has seen few major attacks, either by internal groups or by outside powers, although it remains technically still at war with Israel, only withdrew its troops from Lebanon in 2005 and was named by George Bush, the US president, as part of his administration's so-called "axis of evil".

Attacks by groups inside Syria, which is tightly-controlled by the state and its powerful security forces, are rare. Most have been blamed on Sunni Muslim groups.

From outside Syria, both Israel and the US have been involved in bombing raids on the country.
