The National Police has ordered all personnel to tighten security and remain on high alert following a series of coordinated attacks in Paris on Friday that led to the deaths of more than 120 people.

As more than 290 Indonesians have joined the Islamic State (IS) movement in Syria and Iraq, according to figures from the National Counterterrorism Agency (BNPT), Indonesia is highly vulnerable to similar attacks, particularly as a number of them are suspected to have returned home.

National Police spokesman Sr. Comr. Suharsono said on Sunday that the police force had been ordered to tighten security around the French Embassy in Central Jakarta and other embassies that might face similar attacks.

… According to data presented in March by Nanyang Technological University terrorism expert Rohan Gunaratna, 19 of the 27 militant groups in Southeast Asia that had declared their support for IS were from Indonesia.
