Oil spill washes up on UAE beaches after tanker strike
An oil spill from a tanker attacked near the Strait of Hormuz is spreading along the United Arab Emirates (UAE) coastline, forcing the closure of some beaches and coastal areas.
Satellite images from Monday show the beginnings of the oil spill from a ship matching the location and dimensions of Gem No.2, which was damaged between 9 and 10 October during a record surge of vessel strikes by Iran.
The slick of oil had spread more than 35km (22 miles) from the tanker by Wednesday, the satellite imagery showed.
UAE authorities said on Thursday that the incident is affecting beaches near the northern city of Umm Al Quwain and verified video from Friday shows the oil washing ashore, colouring the water black.
The UAE's Ministry of Climate Change and Environment said on Thursday that it "immediately began containment" in order to "limit environmental impacts".
Prof Steve Widdicombe, director of Sharjah Marine Science Research Centre in the UAE, told BBC Verify it was "inevitable that there will be an impact", but researchers caution it is too soon to assess extent of the damage.
Initially a much smaller oil leak could be seen emerging from the ship on 19 October.
But the slick appears to have rapidly spread over two days, according to radar satellite imagery reviewed by BBC Verify and intelligence firm MAIAR.
Oil spills can cause immediate deaths of marine animals and other organisms, for example by physically trapping turtles, smothering the feathers of seabirds or damaging the gills of fish.
They can also cause longer-lasting damage, Prof Widdicombe said, if species remain exposed to toxic compounds from the oil which could impact their ability to reproduce.
