A delegation from the United Arab Emirates (UAE) has arrived for a first-ever official visit to Israel. Both countries have signed a series of deals - the latest of which is visa-free travel between their nationals. This makes the UAE the first Arab state to reach such an agreement with Israel. Earlier, both sides also agreed to launch 28 weekly flights between the two countries. Prime Minister Benjamin Netanyahu has hailed the visit as "historic." It comes after the United States brokered a normalization agreement.
