The Bali and Jakarta Police Offices have put both destinations on highest security alert following a series of bombings in Surabaya and neighbouring Sidoarjo on Sunday.
Additional security personnel and more stringent security checks are being imposed at Bali’s Ngurah Rai International Airport and all entry points to the island.
Budi Karya Sumadi, Indonesia minister of transportation said the number of security personnel at Jakarta’s Soekarno-Hatta International Airport had been increased from 500 to 700, including members of the bomb squad and bloodhounds.
The situations at both Indonesia’s busiest airports are running as normal.
The suicide bombing took place at three churches in Surabaya, Indonesia’s second biggest business city after Jakarta, almost simultaneously yesterday morning.
Last night, another bomb blast occurred in a flat in Sidoarjo, and another blast took place this morning (08.50 local time) at a police office in Surabaya.
At press time, at least 17 people have died including the nine suicide bombers, plus 45 people injured.
President Joko Widodo strongly condemned the terrorist attacks in East Java, saying they were “beyond humanity measures”.
