Asian shares mostly slip as latest fighting undermines the US-Iran ceasefire

Asian shares mostly declined as renewed US-Iran fighting undermined a ceasefire, with Japan's Nikkei 225 and South Korea's Kospi slipping. Oil prices rose above $90 per barrel, straining fuel markets, while the US and Iran exchanged attacks near the Strait of Hormuz. The Hang Seng and Shanghai Composite bucked the trend with gains.
