Iran’s navy has accused the United States of attacking its Konarak naval base in the southeast of the country early Monday, saying two of its soldiers were wounded in what could mark a fresh escalation in the eight-month-old war.

In a brief statement carried by Al Jazeera, the navy said American forces hit the base with “two light projectiles” and that the intended target was a 35mm cannon.

The facility sits inside a military complex in Sistan and Baluchestan province, on Iran’s Gulf of Oman coastline. Iranian officials have not given further details about the circumstances of the attack or the extent of any damage.

There has been no independent confirmation of the incident. The US military had not commented on the claim at the time of reporting, and US Central Command has yet to confirm responsibility.

Markets reacted quickly. Brent crude climbed above $110 a barrel after earlier losses, as traders worried about further disruption to Middle Eastern energy supplies. Gulf crude flows remain disrupted by tanker attacks, and the reported strike pulled attention back to the risk of a wider supply shock.

The claim is also politically sensitive in Washington. President Donald Trump had earlier said his administration was not planning attacks on Iran ahead of the November 3 midterm elections, so a confirmed US strike would cut against that position.

The incident comes on a day of heavy regional violence. Houthi missiles killed at least 53 recruits at a military camp in Yemen’s Shabwa province, Israel carried out fresh air strikes on southern Lebanon, and Pakistan suspended cross-border trade with Iran over security concerns.
