Authorities in the UAE capital Abu Dhabi, and the neighbouring emirate Dubai, say faulty gas connections have caused blasts which occurred Monday in the Emirates' cities, killing three people. The explosions came on the day of the arrival of a high-level Israeli delegation into Abu Dhabi with the blast in that city occurring at two fast food outlets, the KFC and Hardees, situated on the Airport Road which the delegation travelled on from the airport to the city.
