The US released the following press release on the matter:
The United States strongly condemns the recent attacks by forces under the direction of Ibrahim Jadhran on the oil ports of Ras Lanuf and Al Sidra and the ongoing violence that has damaged Libya's vital oil infrastructure and disrupted oil exports.
We call for all armed actors to cease hostilities and withdraw immediately from oil installations before further damage occurs.
Oil facilities, production, and revenues belong to the Libyan people. The United States believes these vital Libyan resources must remain under the exclusive control of the National Oil Corporation and the sole oversight of the Government of National Accord, as outlined in UN Security Council Resolutions 2259, 2278, and 2362.
