Answer

Concerted effort can mean a) an effort that is planned or carried out by two or more people or groups with a common goal (as in the first sentence) or b) an effort that is made in a serious and determined manner ( as in the second sentence)

As Brad said  'Across Asia' means from all parts of Asia.

Wounded and injured both mean suffering harm or physical damage but wounded is usually only used when the injury is caused by a weapon or in war. In the case of suicide bombs both can be used.

'police mosque' in this news story was a mosque inside a police compound.

Concern takes both 'about' and 'over' and they are used to mean the same. Concern 'for' is also used when the object is a person.

Answer

Regarding your questions about "concerted efforts," yes, you interpreted them correctly.  "Across Asia" means all parts of Asia (e.g., China, Korea, Japan, Vietnam, etc.).

"Injured" and "wounded" mean the same thing: the writer uses synonyms to make the paragraph more interesting (using the same word all the time is boring to the reader).  A police mosque is, I assume, a mosque where the police can pray five times per day, located on the grounds of a police station.

Yes, "concern" usually takes the preposition "about," but the phrase "expressed concern over..." is also correct.
