PARIS ATTACKS

Salah Abdeslam, the last surviving suspect in the November Paris attacks, was captured in Brussels on Friday.

The four-month hunt for Abdeslam has “generated intense criticism of Belgian authorities,” reports the New York Times editorial board, which provides a chronology of the terror suspect’s “time on the run.”

“We got him.” Mary Dejevsky similarly cautions that the success of Abdeslam’s capture should not be allowed to “obscure the shortcomings in Europe-wide detection and law enforcement” that the Paris attacks and subsequent investigations has exposed. [The Guardian]

CHINA and AUSTRALIA

A “scruffy little port” in Darwin, Australia, is “a strategic gateway to the South China Sea,” reports Jane Perlez.

Australia is planning “an extensive arms buildup” in response to growing fears over China. The planned increase in defense spending “could influence the balance of power in the Pacific region,” according to experts. [Washington Post’s A Odysseus Patrick]

Almost 4000 individuals were referred to the UK government’s counter-terrorism scheme last year, according to official figures.
