Oil prices rose more than 2% in early trading on Monday after Israel ordered troops to move further into Lebanon ​in the battle with the Iranian-backed Hezbollah militant group, despite a ceasefire announced more ‌than six weeks ago.

U.S. crude futures rose $2.37 or 2.71% to $89.73 a barrel as of 0028 GMT. Brent futures rose $2.16 or 2.37% to $93.28 a barrel.

The stepped-up fighting, coming just after the U.S.-hosted Israeli-Lebanon peace talks in Washington on Friday, dimmed expectations that the U.S. and Iran could soon announce an extension to their ceasefire agreement, which had driven Brent and WTI to settle down by 1.8% and 1.7%, respectively, on Friday.

The Israel-Lebanon conflict has been the broadest spillover of the Iran war. It started on March 2 ​when Hezbollah began firing rockets and drones across the border into Israel to back its ally Iran.

​The two sides reached a ceasefire in mid-April but have continued to trade fire.

U.S. President Donald Trump said on Friday that he would soon decide on a proposed deal to extend a ceasefire with Iran announced in early April, giving ​negotiators more time to seek a permanent end to the conflict and find a solution to ​the underlying dispute over Iran's nuclear program. Israel would be key to any such deal, and Iran has also said ‌repeatedly ⁠that Hezbollah must be included.

Meanwhile, concerns are rising about mines in the key oil and gas shipping lane, the Strait of Hormuz, IG analyst Tony Sycamore said in a note.

That could slow the process of reopening the strait and mean relief for the oil market comes more slowly, even after it is reopened.

"Even if ​an agreement is reached, ⁠it won't deliver a flood of supply," Sycamore said.

An Axios reporter said on X on Friday that Iran had dropped more mines in the strait earlier ​in the week, shortly after U.S. Defence Secretary Pete Hegseth said that attempts ​to lay ⁠more mines would be a violation of the ceasefire.

Hormuz is a conduit for about a fifth of global oil and gas flows, and Iran has effectively closed it since the conflict began with U.S. and ⁠Israeli strikes ​in February.

Concerns over supply outweighed lacklustre economic data from ​China over the weekend, which showed stalling factory activity. 

This added to concerns that the world's second-largest economy is losing momentum, weighed down ​by a contraction in exports and cost pressures.
