NASA satellite images show that the eruption in the Red Sea in the Zubair archipelago has produced a new island. The island is circular, about 500 m wide and located about 1 km north of Rugged Island. It consists of fresh probably basaltic lava flows and an active vent seems to be in its center.
The same area with no island before
A large steam plume, generated by evaporating sea water at the entry of lava flows into the sea is seen on the satellite image, drifting north.
The island has apparently passed through an explosive Surtseyan phase very quickly, probably because the erupting basalt lava was poor in gas and because the output rate was high, so that the vent could be sealed from water access in short time.

Zubair Group volcano (Yemen) - Smithsonian / USGS Weekly Volcanic Activity Report for 21 December-27 December 2011 (New Activity / Unrest)
An eruption from the northern part of the Zubair Group continued during 21-27 December. MODIS imagery from NASA's satellites on 22 December showed a plume, possibly containing ash, rising from what was thought to be a submarine eruption. Imagery acquired on 23 December from the Advanced Land Imager (ALI) on NASA's EO-1 satellite showed a new island at the location with a plume rising from it, roughly 500 m N of Rugged Island and more than 500 m in diameter. ...

Zubair Group volcano (Yemen) - Smithsonian / USGS Weekly Volcanic Activity Report for 14 December-20 December 2011 (New Activity / Unrest)
According to local news, fishermen from the port city of Salif on the western Red Sea coast of Yemen reported an off shore eruption from the island of Jebel Zubair, about 60 km SW, with lava fountains rising 20-30 m above the summit on 19 December. On 19 December a SO2 cloud was detected in an OMI satellite image. MODIS imagery from 20 December shows a plume rising from a submarine eruption about 1.5 km SW of Haycock and N of Rugged (near the N end of the Az-Zubair island group), and about 12 km NE of Jebel Zubair island. ...
