Kensington Gardens (a major royal park in central London) has reopened after police investigated several suspicious items, including two jars of powdered substance, discovered near the Israeli embassy on Friday. Counter-terrorism officers were responding to an online video posted by Harakat Ashab al-Yamin al-Islamia, an Iran-linked Islamist group, which claimed to have targeted the embassy using drones carrying dangerous substances. The Metropolitan Police confirmed no harmful materials were found, though investigators continue to examine whether the items are connected to the video, while the group is also suspected of involvement in separate arson attacks in north London.
