Police disrupted a terrorist plot to bring down an airplane and arrested four men on Saturday in raids on homes in several Sydney suburbs, the prime minister said on Sunday. Prime Minister Malcolm Turnbull said security had been increased at Sydney Airport since Thursday because of the plot. The increased security measures had been extended to all major international and domestic terminals around Australia overnight. "I can report last night that there has been a major joint counterterrorism operation to disrupt a terrorist plot to bring down an airplane," Turnbull told reporters. Justice Minister Michael Keenan said the plot was the 13th significant threat disrupted by police since Australia's terrorist threat level was elevated in 2014.
