Five small bombs on Tuesday hit the centre of the Yemeni capital, mostly controlled by Shiite militiamen since September, killing one of them and wounding two others, a medic said.
The first explosion went off in the old quarter of Sanaa when one of the militiaman known as Huthis tried to defuse a bomb discovered underneath the car of a judge. He died in hospital, according to the medic.
Another four bombs planted in garbage containers in the same Bustan al-Sultan neighbourhood then exploded within intervals around five minutes, an AFP correspondent reported.
The Huthis, who fought authorities for a decade in their northern stronghold, overran Sanaa on September 21 and have since expanded to coastal areas and southern regions, where they faced Sunni tribes backed by Al-Qaeda militants.
