CAIRO — A shell fired by warring Libyan militias struck an oil tank Tuesday near the capital's international airport, despite local officials saying they struck a cease-fire to allow firefighters to battle an out-of-control blaze at its oil depot, an official said.
The cease-fire agreement, reached late Monday night and mediated by the Tripoli City Council, would mark a rare pause in two weeks of fighting in the capital, a level of violence unseen since the downfall of longtime dictator Moammar Gadhafi in 2011.
However, the shell struck an oil depot tank in Tripoli's Sedi Bu-Salem district, an official with Libya's state-run oil corporation told The Associated Press. The tank didn't catch fire, he said.
The official spoke on condition of anonymity as he wasn't authorized to brief journalists.
Another 13 fire trucks arrived Tuesday to battle the blaze at the oil depot, which has a capacity of 6 million liters (1.6 million gallons). The fire spread to a second depot Monday afternoon, the government said.
Libya's interim government has been urging rival groups to stop fighting, warning that the fire could trigger a "humanitarian and environmental disaster" in Tripoli. It appealed for "international help" to extinguish the inferno. It later said that Italy has agreed to send firefighting airplanes, which the Italian Foreign Ministry denied.
Libyan television stations have called on residents to evacuate areas within a 5-kilometer (3-mile) radius of the airport. Many Libyan families scrambled to leave. Black smoke continued to billow Tuesday over the Tripoli skyline.
The clashes sparked earlier this month forced authorities to shut down the airport after it was devastated in shelling between militias controlling it ever since Gadhafi's fall, and others who accuse them of being Gadhafi's loyalists. The armed confrontations prompted many diplomats and foreigners to flee the country, including the U.S. ambassador in Libya and United Nations staff.
On Tuesday, a Spanish military plane evacuated 60 people from Libya, the Spanish Foreign Ministry said in a statement. The Spanish ambassador will remain in Tripoli with a reduced support staff.
"Spain will not close its embassy in Tripoli as a show of support for the Libyan transition, its institutions and solidarity with the Libyan people in these times of crisis," the statement said.
The cease-fire in Tripoli comes as Benghazi in the far east has been enduring monthslong battles between Islamist-led militias and forces allied with renegade Gen. Khalifa Hifter, who launched a campaign aimed at crushing Islamist extremist militias.
On Tuesday, a Libyan fighter jet crashed after Hifter's forces launched series of nighttime airstrikes, striking positions of Islamist-led militias including those of Ansar al-Shariah. That's the al-Qaida-inspired group the U.S. blames for the Sept. 11, 2012, attack that killed U.S. Ambassador Chris Stevens and three other Americans.
Mohammed Hegazi, a spokesman for Gen. Hifter's so-called National Army, claimed that the fighter jet crashed due to a "technical failure" and that the pilot safely escaped by parachute.
However, the official Facebook page of The Shura Council of Benghazi Revolutionaries, an umbrella group for Islamist-led militias there, claimed responsibility for the "downing" the fighter jet. It said it came in response to the airstrikes.
