Yet, another Drone attack! The drone strikes began many years ago as a mean of targeted operation against terrorism but now they are crucially taking some other means too. Recently, many unknown drone planes have been sighted near many important and crucial locations, and indeed, such unknown drones can be silent threats.

For the last month or two, continuous news has been reported about drone sightings over Paris. Investigations are underway to determine the exact purpose of those drones; however, the unsettling thing is that the drones were sighted over very important buildings such as the Eiffel Tower, military museum and US Embassy.

Interestingly, drones are not only meant to attack but they are also being used for search operations, for aerial photography, for targeted operations and more. Almost all the news channels now possess some drones for aerial photography and live coverage. Recently, a British Journalist has been fined over 1000 Euro as an admonishment for flying his drone over Central Paris. Similarly, a journalist from Al-Jazeera had been arrested last month with his companions for being held guilty by French law of flying his drone over the capital city of France. Considering the harmful effects that a drone may bring, countries are making significant changes in their laws and legislations.

Apart from unknown drone sightings, the known drone attacks are also extending their wings. Recently, a number of drone strikes have been reported in Yemen, targeting some 17 terrorists but actually leading to the killing of around 273 innocent citizens. An analysis about drone strikes conducted by Human-Rights Group indicated that when the drone operators specify "targeted killing of some individuals", they actually heartlessly kill considerably more people than their target.

While drones are considered as a sign of danger, there are various large companies that are using them to ameliorate their businesses. Amazon and Google are working on drones that can deliver the packages to their customers. Interestingly, Facebook also wants to use this technology to carry internet signals to remote areas.
