DAMASCUS - Syria's Foreign Minister Walid al-Moallem challenged the Western powers Tuesday to provide their evidence on the involvement of the Syrian troops in chemical weapons use.

Al-Moallem said at a press conference held Damascus that his government has interest in revealing the reality of the chemical attack that supposedly took place in Damascus' countryside, stressing that the Syrian government has lived up to its part of the deal with the UN but the rebels hindered the mission of the UN inspectors.

Regarding a possible US military attack on Syria, the Syrian top diplomat said that any possible military strike will not affect the government troops' advancement against the rebels.

"Syria will defend itself with all available means if the US decided to attack the country," he stressed.
