The specific detail that the New IRA declared on Tuesday their intent to kill police coming out of the station is attributed to the 'Irish News' within one search result; other sources mention 'murderous intent' generally but don't explicitly quote the Tuesday declaration of intent for that specific action.

The warning about targeting officers at their homes is mentioned in the same source as claim 3. While other sources discuss the history of under-car bombs, the specific current warning is only explicitly detailed in one result.

While sources confirm the Dunmurry attack and the general nature of New IRA activity, the provided evidence does not specifically mention a 'similar attempted car bombing at a police station outside Belfast last month' to corroborate the specific timing and nature of a previous attack.

The detail about Constable Ronan Kerr being the last officer killed 15 years ago by a bomb under his car appears in one search result. No other provided evidence confirms or denies this specific historical fact.
