Indonesian security forces have detained 35 militants for training in Central Java in addition to five in East Java connected with the Jan. 14 Jakarta terrorist attack, according to police officials, Detik reported Feb. 20. Police said the militants are members of Jemaah Ansar Khilafah Daulah Nusantara (JAKDN), an umbrella group that has pledged allegiance to the Islamic State. The Central Java militants had been carrying out exercises using air rifles and bayonets on Mount Sumbing and Temanggung. Local residents reported them to authorities. The five bombing suspects were arrested late Feb. 19 in Malang City for ties to last month's attack in Jakarta, which killed eight people. Despite their purported links to the Islamic State, it is clear from the January attacks that the militants received minimal training and direction from abroad.
