Cameron pledges funds to fight terrorism, bolster cybersecurity

British Prime Minister David Cameron recently pledged approximately $1.9 billion to bolster programs that combat global terrorism and boost cyber security.

Cameron said that the U.K's ability to fight "unseen enemies" is a "national necessity," Sky News reports.

The British intelligence agencies MI5 and MI6 recently identified terrorism, espionage and the proliferation of weapons destruction as the biggest threats to British national security.

In regards to global terrorism, British intelligence said that al-Qaeda in the Islamic Maghreb, the Somalia-based al-Shabaab and al-Qaeda in the Arabian Peninsula pose the greatest risk to the U.K.

The agencies also said that hundreds of Britons could be fighting the Islamic State in Iraq and Syria (ISIS), the extremist group that recently took control of large parts of Iraq. Members of al-Qaeda's Syrian affiliate the al-Nusrah Front, another threat identified by MI5 and MI6, recently swore allegiance to ISIS, according to Sky News.

MI5 and MI6 said that at least 20 foreign intelligence agencies, including Russia and China, are actively operating against the interests of the U.K. Hackers equipped to alter, steal or destroy computer networks, infrastructure or information systems pose a serious threat to the U.K., Sky News reports.

British intelligence also said that nations acting in violation of United Nations resolutions on WMDs are a threat to security, as well as espionage in the realm of information technology, communications and other technology-driven areas, according to Sky News.
