The wife of the Pulse nightclub shooter has been arrested in the US, officials have confirmed.

Noor Salman - the wife of Omar Mateen - was arrested in the San Francisco area.

US Attorney General confirmed the arrest during an interview on MSNBC.

"I can confirm the arrest did occur in this case," she said. "This is an example of the fact that investigations do continue long after they are publicly discussed.

"This is still an ongoing matter - I'm not able to give you much more on that, but I can confirm the ongoing investigation did lead to that arrest," she added.

Details of the charges were not immediately apparent.

Omar Mateen (29) killed 49 people at the gay nightclub in Orlando, Florida in June before being shot dead by officers.
