KABUL (Reuters) - A quiet student at Kabul University, 25-year-old Abdul Rahim has a dream: to join Islamic State in Syria and fight for the establishment of a global caliphate - a new, alarming form of radicalism in war-weary Afghanistan.
"When hundreds of foreigners, both men and women, leave their comfortable lives and embrace Daish, then why not us?" he asked, using a word for Islamic State (IS) common in the region.
