Two suspected terrorists have been arrested under the Terrorism Act in Dover.
Officers from Scotland Yard's Counter Terrorism Command made the arrests late last night at approximately 11pm.
The two men, aged 26 and 44 years old, are currently being held at a south London police station while two homes are reportedly being searched in London and Hertfordshire.
A Metropolitan Police statement said: "On Tuesday 3 June, at approximately 23:00hrs, officers from SO15 Counter Terrorism Command arrested two men... at Dover on suspicion of the commission, preparation or instigation of acts of terrorism under Section 41 of the Terrorism Act 2000.
"They are currently in custody at south London police station.
"Officers are searching two addresses in West London and an address in Hertfordshire as part of the investigation under Schedule 5 TACT."
The arrests come days after police apprehended a man at Heathrow airport in connection with involvement in terrorist activity in Syria.
The 19-year-old British national was arrested by counter-terrorism officers as he attempted to board a plane. It was suspected that he was travelling to Syria to take part in the insurgency.
