Officials in Kuwait say they have arrested an Egyptian who planned to carry out "a terrorist act in the country."

The brief bulletin Saturday on the state-run Kuwait News Agency said the unnamed Egyptian "is suspecting to belong to the organization that is called the Islamic State" group. It did not elaborate.

It wasn't immediately clear if the Egyptian had a lawyer.

The announcement comes ahead of the Shiite commemoration of Ashoura, which marks the death of Hussein, the grandson of the Prophet Muhammad, at the Battle of Karbala in present-day Iraq in the 7th century. Shiites and Sunni Muslims largely live in peace in tiny Kuwait.

Kuwaiti police have promised increased security ahead of Ashoura. Two Iranians were arrested in recent days for taking "suspicious" photographs ahead of the commemoration.

An Islamic State-claimed suicide bombing in 2015 targeting a Shiite mosque in Kuwait City killed 27 people and wounded scores.
