The 1915 Çanakkale Bridge in northwestern Turkey is well on its way to becoming the world's longest suspension bridge with towers taller than the Eifel Tower, a significant landmark of Paris.

Istanbul is witnessing a rise in the number of jellyfish on its shores, especially in the Bosphorus Strait, which connects the Aegean Sea to the Marmara Sea, due to strong winds drawing ocean currents.

"There is a high concentration of jellyfish off Arnavutköy and Sarayburnu," said Melek İşinibilir Okyar, an academic from Istanbul University.

The Bosphorus Strait that divides the continents of Europe and Asia in Turkey's largest city of Istanbul turned turquoise over the weekend, with experts saying it was due mostly to the powerful northeast wind.

Seagoing passenger service from the Turkish metropolis Istanbul to other cities has been suspended over the coronavirus outbreak, Istanbul's provincial governor announced on March 30.

Turkey held its first tender on March 26 for Kanal Istanbul, a mega-infrastructure project involving the construction of a 45-kilometer shipping canal in Istanbul parallel to the Bosphorus Strait, state-run Anadolu Agency reported.

The co-founder and honorary president of one of Turkey's foremost non-profit environmental organizations, Hayrettin Karaca -- or as he was known, Grandpa Earth -- died on Jan. 20 at the age of 97.

The Environment and Urbanization Ministry on Jan. 17 approved the report on environmental impact of Turkey's planned megaproject, Kanal Istanbul, an official said.

President Recep Tayyip Erdogan had suggested it in the past but he made it clear in an interview with CNN-Turk TV: Turkey wants to change the status quo in the Bosporus, putting an end to the free passage of vessels using the strait as set out in the 1936 Montreux Convention.
