A Libyan militia has agreed to hand back four oil terminals it captured and shut down last summer in its demand for a share of oil revenues.

Ibrahim Jedran, the leader of the militia calling for more autonomy for eastern Libya, signed the deal on Sunday.

The seizure and shutdown of the terminals has cost Libya billions of pounds.

The agreement followed months of tension, worsened by a bid by the militia to export oil in a North Korean-flagged tanker.

Justice Minister Salah Margani said the militia would immediately hand over the Zuwaitina and al-Hariga terminals, with the Ras Lanouf and Sidra facilities returning to government control later.

In return, an investigation will be conducted into alleged government corruption in oil sales and ways in which to more justly distribute oil money.
