Facebook apologises as services including Instagram hit again

Facebook says there are problems with its services again, days after a major outage hit WhatsApp, Instagram and Facebook for some six hours.

"We're aware that some people are having trouble accessing our apps and products," the firm said.

"We're working to get things back to normal as quickly as possible and we apologize for any inconvenience."

The current problems seem to be affecting the photo and video-sharing platform Instagram in particular.

The firm said in a tweet: "We know some of you may be having some issues using Instagram right now. We're so sorry and are working as quickly as possible to fix."

On Monday, Facebook - which owns WhatsApp and Instagram - blamed an internal technical issue for the major outage which not only affected the firm's services, but also employees' work passes and email.

The services were down from about 16:00 GMT until around 22:00 on Monday.
