Two explosions went off near the US Yokota Base in western Tokyo last night. Police believe the attacks may have been extreme leftist groups. The Japan Times reported:
…There have been no claims of responsibility, but police believe it may have been a guerrilla attack by extreme leftists, Jiji Press and other media said.
Broadcaster NTV reported police were concentrating their investigations on the Revolutionary Labourers’ Association Anti-Majority Faction because the incident came just hours after they arrested a top-ranking member on Thursday.
Via the Air Force Times:
“We can confirm there was an improvised mortar launch outside Yokota over the evening,” Pacific Air Forces spokeswoman Maj. Jillian Torango said in en email Thursday to Air Force Times. “There were no injuries and thus far we have found no damage or impact points here on base.”
The Air Force is assisting the Japanese National Police, who are looking into the matter, Torango said.
The incident comes after a suspected mortar attack on Yokota Air Base in March when police found two launching tubes about 328 yards west of the base, Stars and Stripes reported on March 15.
The launchers were similar to one used to launch a projectile against Camp Zama in November 2012.
