Suspected ISIS militants arrested in Kuwait and the Philippines were planning to carry out bombings against US military forces in Kuwait, the Gulf country’s al-Rai newspaper reported on Monday.

The suspects were also plotting a suicide attack on a hussainiya, or Shiite Muslim meeting hall, said al-Rai, which has close ties to the security services.

Philippine security forces arrested a Kuwaiti and a Syrian for suspected links to Islamic State on March 25, three months after they arrived in Manila.

Al-Rai said Kuwaiti security forces also arrested a Syrian chemistry teacher suspected of involvement with the plots.

A spokesman for the US Embassy in Kuwait referred queries to Kuwaiti authorities. Kuwaiti security officials did not immediately respond to a request for comment.

Kuwait, home to several US military bases, suffered its deadliest militant attack in decades when a Saudi suicide bomber blew himself up inside a packed Shiite mosque in June 2015, killing 27 people. ISIS claimed responsibility.
