DAMASCUS - Syria accused the United States and Western countries on Saturday of colluding with al-Qaida-linked militants to target the country, in the wake of a string of explosions in Damascus and Aleppo the government has blamed on foreign-backed fighters.

"Western countries and the United States, which made alliances to wage wars using the pretext of fighting terrorism, are now making alliances with the terrorists which Syria has been facing," Information Minister Adnan Hasan Mahmoud told journalists in Damascus on Saturday.

He said attacks such as a deadly twin car bombing in Damascus on Wednesday which killed 55 people showed that elements linked to the global militant group al-Qaida were targeting Syria.

"This terrorist escalation using booby-trapped cars with tons of explosives to target the Syrian people ... is a continuation of the bloody terrorist tactic used between armed groups and al-Qaida, along with the international Western countries that support them with weapons and money," he said.
