Madrid--Four family members, including two children, were found dead in an apartment in Gibraltar, local media reported Monday.
The dead are not believed to be residents of the tiny British territory, the online edition of the Gibraltar Chronicle reported.
Police have cordoned off the area and will make a public statement later.
Gibraltar, a self-governing British overseas territory located on Spain's southern tip, measures just 6.8 square kilometres (2.6 square miles), and is home to about 30,000 people.
