Incident: Pro Alliance attacked

The oil tanker Pro Alliance is fired on in the Gulf of Aden 45NM southeast of the port of Aden.

The Yemeni Coastguard responded to the distress call and dispatched a gunboat. The coastguard exchanged gunfire with the gunmen on the skiff, forcing them to flee the area and allowing the tanker to continue its transit. Later, a Spanish frigate boarded a suspicious skiff matching the description and conducted an inspection, but found no evidence of unlawful activity.
