Apple, attempting to get back to the business of introducing new products as it fights with the US Justice Department in court, announced a March 21 event where the company is expected to unveil a smaller-screen iPhone and an updated iPad.

The long-expected unveiling will be held at Apple's campus in Cupertino, California, the company said in the emailed invitation, without providing any other details.

Apple will introduce an updated iPhone with a 4-inch screen, a person familiar with the details has said. The smaller handset will look similar to the iPhone 5s introduced in 2013 and come with updated components, including the company's speedier A9 processor that's currently in the iPhone 6s. An update to the iPad lineup also is anticipated.
