The National Security Council is meeting this afternoon to review Ireland's security arrangements following the Brussels attacks.

The council includes the Garda Commissioner, the Chief of Staff of the Defence Forces, and the heads of four government departments.

It is understood that such meetings are often held in the wake of international terrorist incidents.

The acting Taoiseach Enda Kenny and other ministers will be briefed on the meeting's findings later this afternoon.

It is still believed that no Irish people have been killed or injured in the Brussels attacks.
