Police in Northern Ireland on Tuesday charged two men over a foiled mortar bomb attack on a police station in the the province's second city of Londonderry.
Police intercepted a van primed with four live mortar bombs on Sunday, just minutes before paramilitaries were about to fire them.
The two men, aged 35 and 37, were charged with possession of explosives with intent to endanger life, possession of articles for terrorist purposes and conspiracy to cause an explosion.
They will appear before Londonderry Magistrates Court on Wednesday.
Two other men, aged 31 and 37, were released without charge, police said.
The mortars were found in the back of the van, which had a section of its roof cut back to fire the bombs in a plot to strike a nearby police station, a senior officer said.
A 1998 peace agreement brought an end to three decades of sectarian violence between Protestants and Catholics known as the Troubles, but sporadic bomb threats and murders by dissident republicans continue.
