A series of deadly explosions rocked Brussels on Tuesday, targeting the Belgian capital's main airport and metro system. Christians across Brussels have called for prayer. The coordinated attacks came as the city was on a high level of alert following the arrest of Paris atrocity suspect Salah Abdeslam last week. The Archbishop of Canterbury said: ‘In the great Holy Week of Christian prayer and mercy, the Brussels attacks shock all those who seek peace and justice through the terrible cruelty and utter separation from all that is of God. Once again we see the contrast between the vain efforts to terrify through indiscriminate murder and the call of God to us to show mercy, seek peace and pursue it. Let us at every service this week pray for those caught up in the traumatic events at the airport and in the city of Brussels.’
