British authorities arrested seven anti-war protesters Monday after demonstrators said they boarded a plane at a Scottish airport to search for evidence of US weapons being transported to Israel.
Police said two men and a woman were arrested after getting on the plane at Prestwick Airport, near Glasgow. Four other people were arrested at the airport at around 3:30 a.m. (0230 GMT).
Anti-nuclear campaign group Trident Ploughshares said its activists had boarded a US plane to search for evidence of arms shipments to Israel.
The seven arrests follow those of four other members of the group, who ran onto a runway at the airport on Sunday.
Last month, a stopover at Prestwick of US flights carrying missiles to Israel sparked intense criticism in Britain.
