Amidst reports referring to the increase of foreign gunmen who are fighting by the side of the armed terrorist groups in Syria, the Australian authorities abolished passports of twenty citizens.

The Australian authorities accused the twenty arrested citizens of involvement in violent acts stemming from political motives outside the country, which constitutes a threat to the Australian security due to \'the Jihadist mentality\', according the British newspaper, Guardian.

The accusations come as a result of the international and regional increasing fear of the growing number of "foreign Jihadists" who infiltrate through Turkey under the sight of the Turkish authorities into Syria for fighting by the side of the terrorist and extremist groups including Jabhat al-Nusra.

The European and Western warnings of foreign citizens\' influx are increasing, as big numbers of them are joining the armed groups in Syria after using \'safe houses\' in south Turkey as a center for infiltration into the Syrian territories.
