A suicide bomber rammed a car full of explosives into a blast wall in the Afghan capital on Wednesday, an interior ministry spokesman said.

Sediq Sediqqi said that there was only one attacker, dismissing reports that more than one insurgent was involved in the assault against a housing compound for westerners.

Police chief Ayub Salangi told Reuters the car bomb exploded on Jalalabad road, the main road out of the capital heading east, where several U.S. military bases and compounds housing Westerners are located. A guard and five civilians were killed.

Salangi said one of those compounds, known as "Green Village", was the target.

Hours earlier, President Barack Obama left Kabul following an unannounced visit during which he signed a strategic partnership agreement.

Afghan media said heavy casualties were feared.

A second blast struck the area later, a Reuters witness said. An Afghan official told the Associated Press that 3 explosions occurred in the eastern part of the capital.

A spokesman from NATO headquarters in the country said it was aware of several explosions. Reuters witnesses in the center of the city also heard the blast.

Obama left earlier after making a televised address to Americans from Bagram Air Base north of the capital.

A U.S. embassy warning system urged staff to stay away from windows and take cover. The embassy is in the main diplomatic area in the center of the city.
