UK: UNSC must respond to Iran’s "destabilising actions"

"The Council must respond to Iran’s destabilising actions & lack of respect for international law," Raab said on Twitter, referencing a letter sent to the U.N. Security Council on Tuesday signed by Britain and other nations.

Tehran has denied any involvement in Thursday's attack on the Mercer Street - a Liberian-flagged, Japanese-owned petroleum product tanker managed by Israeli-owned Zodiac Maritime. Two crew members, a Briton and a Romanian, were killed.
