A couple have been treated for shock after a petrol bomb exploded at their Armagh home.

The device was left on a ledge outside a bathroom window at a house at Lonsdale Villas.

The explosion, at about 0030 GMT on Tuesday, smashed the window and set the curtains on fire, causing smoke damage to the room.

It is thought the device had been attached to a firework.

The attack comes less than 48 hours after a pregnant woman had to be treated for shock following a petrol bomb attack at another house in the city.

It happened in the Lisannally Gardens area of the city at about 2045 GMT on Sunday.

The device was thrown at the front door causing minor scorch damage.

Local people said the woman had only moved into the house at the end of last week.
