FOUR peace activists were arrested yesterday after blockading a military convoy transporting nuclear weapons through Scottish streets under the cover of darkness. 

The four were picked up after briefly halting nuclear warhead-laden lorries near Loch Lomond in the early hours of yesterday morning.

Monitoring group NukeWatch said they believed the four converted lorries — part of a convoy of more than 20 military vehicles — were carrying around half a dozen warheads.
