The UK's security minister said today that the country is facing an increased terror threat with the Islamic State network losing ground in Syria as militants are looking to carrying out attacks at home. Ben Wallace said terrorists are trying to carry out attacks in the UK and Europe is under constant attack because they are either unable to join ISIS overseas or had returned from there. <br/><br/>His comments came after ISIS claimed responsibility for the attacks in Spain killing 14 people. The terror group lost its Mosul stronghold to Iraqi forces last month and international efforts to bring down its so-called capital, Raqqa, in Syria continue.
