Sept 1 (Reuters) - Ukraine's President Volodymyr Zelenskiy warned airlines and insurance companies on Tuesday that the presence of Ukrainian drones had made Russian skies dangerous to use and that they were effectively closed.

"Today, we want to warn every airline that uses Russian airspace, every insurer, everyone who still uses key Russian airports: the Russian sky is becoming completely dangerous," Zelenskiy said in his nightly video address.

Ukraine poses no threat to civil aviation, he said, "but there will be drones in Russia's skies and due notice must be taken".

ANKARA, Sept 2 (Reuters) - NATO member Turkey would consider taking its relations with the China and Russia-led security bloc, the Shanghai Cooperation Organisation, to a higher level, PresidentTayyip Erdogan said on Wednesday.

"Turkey's prospect of (full) membership to the organisation does not imply a breakaway from any other bloc or from the West," Erdogan said, according to a transcript of remarks he made to journalists on his return flight from Kyrgyzstan.

Erdogan attended a summit of the SCO, of which Turkey is a "dialogue partner", in Bishkek on Tuesday.

President Donald Trump said US forces staged a "very heavy attack" on Iranian targets overnight and are "prepared to do another one any time we want".

Tehran's security chief warned that Iran had adopted a "new strategy" in the war that began in late February with US-Israeli attacks on the Islamic Republic.

LONDON, Sep 2 (Reuters) - The United States launched a new wave of attacks on Iran late on Tuesday six months into a deadlocked conflict, prompting Iranian missile fire at what it called U.S. assets in Jordan, Bahrain, Kuwait and Iraq.

WASHINGTON, Sept 1 (Reuters) - The U.S. military said late on Tuesday it completed its latest wave of strikes on Iran, saying it struck Islamic Revolutionary Guard Corps targets as the Iran war escalated following a weekend exchange of fire.

U.S. forces struck IRGC targets "including air defense sites, radar systems, maritime assets and facilities, mine laying capabilities, and communications sites," the U.S. Central Command said on X.

The United Nations said Wednesday the 1.5C target would be missed and outlined how global temperatures might be brought back down in a first-of-its-kind assessment met with dismay in climate-vulnernable nations.

UN Secretary General Antonio Guterres last year acknowledged the inevitability of overshooting 1.5C in the next few years but this assessment is the first by a UN agency to unambiguously state the target would be breached.
