The international OPCW inspectors have entered Douma and begun searching for answers over the suspected chemical attack. It's now been eleven days since this attack is said to have taken place. CGTN's Alaa Ebrahim is in Damascus and reports on the confusion about what really happened in Douma -- and the Syrian army's next move.

ALAA EBRAHIM DAMASCUS Syrian state media is reporting that inspectors from OPCW entered the town of Douma on Tuesday. This came as something of a surprise after Russian officials earlier said the team would be allowed in on Wednesday. And of course, it comes after Western nations complained about the experts being denied access to the site of the alleged chemical attack, due to security concerns raised by Syria.

The experts are expected to start collecting soil samples and interviewing local eyewitnesses. Our CGTN team has been to the site of the alleged chemical attack that rebel sources say killed scores more than a week ago. And from our experience there we expect the inspectors might have a difficult task ahead. We heard many conflicting accounts from eyewitnesses and even from doctors who treated the injured.

One doctor at Douma's hospital said many of those he treated suffered suffocation because of debris and not chemical agents. Some accused the rebels of denying them medical care. While the rebels accuse the government of launching the attack.

Meanwhile, Syrian army units are reportedly getting ready to storm the Yarmouk district south of the capital. The former Palestinian refugee camp is the last stronghold for ISIL and al-Nusra Front militants near Damascus. Syrian military sources say the battle ahead won't be easy but -- according to one field commander -- 'recent gains and expertise gained in Ghouta will provide enough momentum for a swift victory'.

And as Syria celebrated its independence day, a false alarm before dawn on Tuesday caused more tension. Aerial defenses detected what appeared to be a missile strike in the Homs area - leading the SANA news agency to report an "outside aggression". The agency later corrected the report without offering details on what caused the false alarm.
