UK shares rise on Israel-Iran ceasefire relief

June 24 (Reuters) - London stocks climbed on Tuesday in broad-based gains after a ceasefire between Israel and Iran came into effect, ending a 12-day conflict that temporarily spiked oil prices and dampened investor risk sentiment.

The internationally focussed FTSE 100 .FTSE rose 0.4% by 1000 GMT, while the domestically focussed FTSE 250 midcap index .FTMC gained 0.9% to touch a more than one-week high.

Travel and leisure .FTNMX405010 stocks led sectoral gains, boosted by airline stocks, as oil prices dropped to their lowest in two weeks.

British airways owner IAG ICAG.L and Easyjet EZJ.L surged more than 5%, while midcap constituents Wizz Air WIZZ.L and Jet2 JET2.L added 3.1% and 3.2%, respectively.

Cruise operator Carnival CCL.L rose 5.6% to the top of the mid-cap index. Hotel chain operators Intercontinental Hotels IHG.L and Whitbread WTB.L gained about 2% each.

However, the truce, announced hours earlier by U.S. President Donald Trump, remained shaky with the Israeli Defence Minister saying he had ordered new strikes in response to Iran's ceasefire violation. Tehran declined the charge.

Crude prices fell on the ceasefire news and weighed on energy giants BP BP.L and Shell SHEL.L, which dropped 4.2% and 2.6%, respectively.

Precious metals miners .FTNMX551030 also declined 2.2% tracking a slide in prices of gold, which is often seen as a safe-haven asset. GOL/
