Police say two people were shot during a night of sectarian rioting in Belfast.

The Police Service of Northern Ireland said Tuesday that Protestant rioters attacked homes in the Short Strand Catholic enclave with bricks, stones, fireworks and fire bombs.

Catholic leaders said Monday’s violence was unprovoked, but Protestant leaders said Protestant homes also were attacked.

Police said up to 500 people were involved in the violence, with shots fired from both sides. Two men suffered gunshot wounds to the legs.

Sectarian tensions typically flare in the build—up to July 12, a divisive holiday when tens of thousands of Protestants from the Orange Order brotherhood march across Northern Ireland.
