A US airstrike has killed Islamic State's top man in Libya, the Pentagon has announced.
The target of the air raid was was named as “Abu Nabil, aka Wissam Najm Abd Zayd al Zubaydi, an Iraqi national who was a long-time al-Qaida operative”.
US high command say Nabil's death will "will degrade [Isis’s] ability to meet the group’s objectives in Libya”.
"While not the first US strike against terrorists in Libya, this is the first US strike against an Isil leader in Libya and it demonstrates we will go after IS leaders wherever they operate," a Pentagon spokesman said.
The Libyan government has confirmed the identity of two new suspects in the investigation into the Lockbie bombing.
A spokesman for the government in Tripoli named the Libyan pair as Abdullah al-Senussi, Colonel Gaddafi's former spy chief, and Mohammed Abu Ejaila, who was named widely in earlier reports as Abu Agila Mas'ud.
The Tripoli official said the Libyan attorney general's office had not been officially informed about the two suspects.

Scottish prosecutors want two Libyans they have identified as suspects in the investigation into the Lockerbie bombing to be interviewed by police.
The pair, who ITV News understands to be Colonel Gaddafi's former spy chief Abdulla al-Senussi and Abu Agila Mas'ud, are currently being held in a Libyan jail.
Both were imprisoned after the fall of Gaddafi and al-Senussi is awaiting the death sentence.
Scotland's Lord Advocate Frank Mulholland QC recently met US attorney general Loretta Lynch in Washington.
They have requested assistance from Libyan authorities for Scottish police and the FBI to interview the two suspects in Tripoli.
The Crown Office has not confirmed the names of the two individuals they are seeking to interview.
Abdelbaset al-Megrahi - the only person convicted over the 1988 atrocity in which 270 people died - was released on compassionate grounds in 2009 and died three years later.
The father of one of the Lockerbie victims has told ITV News he is unsure if Libya was involved in the atrocity.
Dr Jim Swire, whose daughter Flora was killed in the bombing, said: "We're not satisfied the one man who was found guilty was, in fact, guilty.
"So we don't know if the Libyan regime was in any way involved or not, and we've always said that."
ITV News' UK Editor Rohit Kachroo reports:
Sir Malcolm Rifkind has welcomed news that investigators have identified two new suspects in the Lockerbie bombing.
Sir Malcolm, who was Scottish secretary at the time of the 1988 massacre, told ITV News he hoped it would serve as a message that justice would be served no matter how much time had passed.
The bombing of Pan Am Flight 103 almost 27 years ago killed 270 people, making it the deadliest terror attack ever on British soil.
ITV News understands the two suspects are Colonel Gaddafi's former spy chief Abdulla al-Senussi and Abu Agila Mas'ud.
The two suspects in the Lockerbie bombing are Colonel Gaddafi's former spy chief Abdulla al-Senussi and Abu Agila Mas'ud, ITV News understands.
Al-Senussi is also suspected of involvement in the murder of Pc Yvonne Fletcher outside the Libyan embassy in London in 1984.
Both are currently being held in a Libyan jail.
Reacting to the major development in the Lockerbie bombing investigation, the SNP's Westminster Leader Angus Robertson told ITV News:
It doesn't matter if it's 25 years after an atrocity.
I think justice must be served and if there are people that have questions to answer, they should answer to Scottish and US authorities.
It's good that progress is being made.
A "real effort" must be made to get to the rest of those involved in murdering 270 people in the 1988 Lockerbie bombing, a stepmother of a victim has said.
Rosemary Wolfe's stepdaughter Miriam was just 20 when she was killed in the attack.
"They've [the two suspects] probably been around for years and nothing has been done so we think it's high time a real effort was made to get to the rest of the truth and to get to those involved," the American told ITV News.
The mother of a victim of the Lockerbie bombing has told ITV News that she is "delighted" that Scottish and American investigators have identified new suspects.
American citizen Susan Cohen lost her 20-year-old daughter Theodora when Pan Am flight 103 heading from London to New York exploded over the southern Scottish town of Lockerbie.
"I'm delighted that they are doing this - we the American families have been pressing and pressing for the bombing to be properly investigated," she said.
"I want to make it clear that I think Megrahi did it but the trial was framed too narrowly.
"The governments have been dragging their feet and they should have been looking for other people involved, because it wasn't just Megrahi."
