FBI team set to arrive in Lebanon to participate in probe into Beirut explosion

A team of FBI investigators is due to arrive in Lebanon this weekend to take part in the probe of Beirut’s massive explosion, a senior U.S official said on Saturday after visiting the location of the blast.

David Hale, U.S. undersecretary of state for political affairs, called for a thorough and transparent investigation. He said the FBI team is taking part at the invitation of Lebanese authorities in order to find answers about what caused the Aug. 4 explosion which killed nearly 180 people and wounded thousands.

The cause of the fire that ignited nearly 3,000 tons of ammonium nitrate at Beirut’s port remains unclear. Documents have emerged showing the country’s top leadership and security officials were aware of the chemicals stored at the port. French investigators are also taking part in the Lebanese-led probe.

“We really need to make sure that there is a thorough, a transparent and credible investigation. I know that is what everyone is demanding,” Hale said.

Search and rescue crews flew in from around the world in the immediate aftermath. Hale toured the site of the blast with Lebanese army officers.

Many Lebanese want the probe taken out of the hands of their government, fearing that bickering among the long-entrenched political factions, notorious for corruption, won’t allow any results to come to light that are damaging to their leadership.

Top Lebanese officials, including President Michel Aoun, have rejected calls for an independent probe, describing it as “a waste of time” that would be politicized.

Late Friday, the leader of the powerful Hezbollah group said that he did not trust any international investigation, in a clear reference to the FBI assistance. Hassan Nasrallah said the cause of the explosion is still unclear, adding that any international probe would also have to clear Israel of any responsibility in the port explosion.

Nasrallah added that Israel will be met “with an equally devastating response” if the investigation points to its involvement.

Israel has denied involvement and so far no evidence has emerged suggesting otherwise. However, Aoun, who is supported by Hezbollah, has said it’s one of the theories being investigated.

Hale also stressed the need for full state control over ports and borders, in an apparent reference to claims that Hezbollah holds influence over both in Lebanon.

“We can never go back to an era in which anything goes at the port or borders of Lebanon,” he said.

Under pressure, Lebanon’s government resigned on Aug.10. For now, there are no formal consultations underway on who will replace Hassan Diab as prime minister and no likely candidate has emerged. But the flurry of diplomatic visits appeared designed to influence the forming of the new government.

Popular anger has swelled over the ruling elite’s corruption, mismanagement and political uncertainty. Western leaders have said they will send aid directly to the Lebanese people and that billions of dollars will not be pumped into the country before major reforms take place.

On Friday, the United Nations launched a $565 million appeal for Lebanon with immediate humanitarian assistance and initial recovery efforts.

Washington and its allies consider Hezbollah a terrorist organization, and have accused the Iran-backed group of abusing government funds. Local media have speculated that Hale would be pushing for a government that excludes Hezbollah.
