Apple releases small new iPhone, iPad for business use

The new phone — the iPhone SE — is an upgrade to the older, four-inch iPhone 5S, released in 2013. It’s aimed at consumers who haven’t sprung for the bigger-screen iPhone 6 models that Apple introduced over the last two years.

The attack came as Turkey had heightened security across the country in the run-up to a Kurdish spring festival where Kurds in Turkey traditionally use to assert their ethnic identity and demand greater rights.
