Two US cargo aircraft carrying weapons for Israel are due to make stop-overs at a Scottish airport over the weekend with the approval of the British government, airport authorities said Saturday.
The two Boeing 747s are carrying "dangerous material" from Texas to Tel Aviv, and have been given authorisation to land, the Civil Aviation Authority (CAA) said.
"They are hazardous material flights: the items that they are carrying are understood to be of a dangerous nature," a spokesman said.
"They are landing at Prestwick (near Glasgow) for refuelling, and needed an exemption to be able to land in the UK. This was granted last week."
On Friday US President George W. Bush apologised to British Prime Minister Tony Blair for failing to observe proper procedures last weekend when two aircraft carrying bombs for Israel transited through Prestwick, according to a British spokesman.
The planes were described as civilian flights and the US did not notify the British authorities of their cargo, which, according to one newspaper report included bunker-busting high explosive bombs.
British Foreign Secretary Margaret Beckett made public her unhappiness at the time.
A demonstration is planned at Prestwick Sunday.
