A group of military defectors called the Free Syrian Army has claimed responsibility for Wednesdayâ€™s attack on an air intelligence base in Harasta, an eastern suburb of Syriaâ€™s capital.
It says it has declared war on the regime of President Bashar al-Assad and â€śis capable of striking them in any place and at any time we want.â€ť
The group emerged amid an eight-month-long crackdown on protesters by the Syrian government, a grinding civil conflict that the United Nations says has left more than 3,500 people dead.
The Free Syrian Army has reported recent operations in other cities, including Hama, Homs and Daraa, but the sophistication of Wednesdayâ€™s attack signals â€śa new era of the conflict,â€ť said Andrew Tabler, a Syria expert from the Washington Institute for Near East Policy.
â€śUntil now,â€ť Tabler added, â€śmost of the protests have been peaceful.â€ť
