Jakarta/Surabaya. Muhammad Nadir Umar, member of East Java's Pasuruan Legislative Council, or DPRD, from the Prosperous Justice Party, or PKS, was deported from Turkey for allegedly attempting to enter Syria to join the Islamic State militant group.

Nadir, who flew on the Air Asia's XT327 flight from Kuala Lumpur, arrived at Juanda International Airport in Surabaya, East Java, on Saturday (08/04) and was immediately taken by police for questioning.

"We are still questioning him in accordance with procedures that also involve [the National Police's antiterror unit] Densus 88, the Ministry of Social Affairs and the National Antiterrorism Agency [BNPT]," a police source said on Sunday.

Nadir allegedly attempted to join the Islamic State through a platform of a humanitarian mission from Quari Umah Foundation for Turkish and Lebanese refugees in Syria.

People who want to join the Islamic State cannot be charged under Indonesian law, the source added.

On the day of Nadir's arrival, police killed six alleged Islamic State militants, after a drive-by shooting targeting officers.
