A shadowy Islamist group which claimed responsibility for a suicide bombing near a British school in Qatar has vowed to carry out attacks against oil installations, churches and Western military bases in the Middle East, in two statements posted on the Internet Tuesday. Singling out the United States, Britain and Italy as potential targets, the Jund ash-Sham Organization, (Organization of Soldiers of the Levant) said the attack in the Qatari capital Doha was "only the beginning" and a "big surprise" was coming. There was no way to verify the authenticity of the two statements. They followed a statement attributed to the group and also posted on an Islamist website Monday claiming Saturday's attack in Doha, which killed a Briton and injured 12 people.Addressing its "cells in Ash-Sham and Mohammed's (Arabian) peninsula," the group called for "striking at the enemies of God while sparing civilians." "Hit their bases and churches," the group told its followers, decrying the presence of "crusader military bases, containing churches and idols, across the land of Islam." The group suggested it would not spare France, saying: "We tell all our cells to hit oil [facilities], military bases and churches and prevent them from entering mosques through martyrdom (suicide) operations, as they prevented us from [wearing] the hijab (Islamic veil) in France." The car bombing in Doha, which the group said was carried out by one of its "lions," occurred outside at a theater affiliated with the British school.
