An explosion was heard in Baghdad early Wednesday, an AFP journalist said, as Iraqi officials reported a drone and rocket attack targeting the US embassy.
The latest explosion came hours after multiple blasts were heard across the Iraqi capital, where a witness told AFP he saw detonations likely caused by air defenses intercepting projectiles over the embassy.
Diners at a restaurant in the city seemed undisturbed by the initial sounds of the blasts.
Another witness saw a fire on the edge of the embassy grounds from her balcony, and a security official said the blaze was caused by a drone.
"The embassy was the target of a drone and rocket attack," the official said, speaking on condition of anonymity.

Another drone, targeting a US diplomatic and logistics center at Baghdad's airport, was shot down, according to another security official.
Hours later, an AFP journalist heard another explosion, with a security official saying "a drone directly hit the embassy".
The official did not specify whether there had been any casualties or damage.
