Aug 7 (Reuters) – European shares edged higher on Friday, led by healthcare stocks, though rising oil prices ‌and renewed Middle East tensions kept risk appetite ‌in check.

The pan-European STOXX 600 rose 0.2% to 659.59 points by 0731 ​GMT, and was on track for a fourth consecutive weekly advance.

The return of geopolitical concerns has tempered the optimism that drove markets to record levels earlier this week, with ‌investors weighing the ⁠inflationary impact of higher energy prices ahead of a key U.S. jobs report later in ⁠the day.

Brent futures extended gains, rising $83.29 a barrel on further concerns around the opening of the Strait of Hormuz. Iran, ​working with ​Oman, suggested banning vessels ​deemed hostile from the strait ‌and heavily fining those that violated the proposed rules. [O/R]

Focus will now turn to U.S. payrolls data for clues on the interest-rate outlook. U.S. job growth is expected to have accelerated in July, underscoring the resilience of the ‌labour market and giving the Federal ​Reserve room to remain focused on ​inflation.

Earnings also drove ​market moves. Insurers led sectoral declines, falling 0.6%, ‌after Munich Re slid 3.7% ​despite reporting ​a 6% rise in second-quarter net profit, beating expectations of a decline.

Healthcare stocks led gains, rising 1.3%. Genmab ​jumped 7.2% after ‌the cancer drugmaker reported higher first-half revenue and ​raised its full-year outlook.
