June 24 (Reuters) -

Canada's main stock index edged higher on Tuesday after U.S.

President Donald Trump announced a ceasefire between Iran and

Israel, while losses in heavyweight mining shares kept overall

gains in check.

The S&P/TSX Composite Index advanced 0.3% at

26,686.38 points.

The truce, however, remained shaky as Trump accused both

nations of violating the ceasefire agreement.

Israel acknowledged that it hit Iran's radar in retaliation

for Iranian missile launches but said it had refrained from

attacks beyond that.

Tehran has rejected accusations of breaching the truce.

"It's going to remain choppy just because there's going

to be volatile news...every hour there's news released one on

top or the other that's moving markets," said Josh Sheluk,

portfolio manager at Verecan Capital Management.

On the TSX, mining stocks fell 1.8% after gold

prices declined nearly 2%.

Gold miners were among the top decliners on the index,

with G Mining ( GMINF ) and SSR Mining ( SSRGF ) falling 5.4%

and 4.9%, respectively.

The energy sector lost 0.3%, tracking a fall

in oil prices.

On the flip side, information and technology

rose 1.6%.

Shares of e-commerce firm Shopify ( SHOP ) gained 4%,

rising for the third straight day and offering the biggest boost

to the benchmark index.

Canada's annual inflation remained unchanged at 1.7% in May,

with a drop in gasoline costs keeping the overall index stable.

May and June's inflation data, expected before the Bank of

Canada's policy meeting in July, will be factored into any rate

decision on July 30.

Canada and Europe agreed to deepen security ties ahead of

the NATO summit in the Hague.
