(AP Photo/Thibault Camus, File)BEIRUT Lebanese President Michel Aoun says the probe into a devastating blast in Beirut is very complex and wont be finished quickly.
Responding to calls that he step down, Aoun told French TV station BFMTV in his first interview with foreign media since the Aug. 4 blast that it would be "impossible" because it would create a power vacuum.
The cause of the fire that ignited nearly 3,000 tons of ammonium nitrate stored at Beiruts port remains unclear.
We had the determination to reach conclusions quickly but we found out that the issues are very complex and require time, said Aoun.
Hezbollah leader Hassan Nasrallah has denied his group has any role in the explosion and said any international probe would likely seek to clear Israel of responsibility in the port explosion, if it had a hand.
