BEIRUT — The evacuation of more than 3,000 Syrians that was scheduled to take place Sunday from four areas as part of a population transfer was postponed, opposition activists said, a day after a deadly blast that killed more than 120 people, many of them government supporters.

The reasons for the delay were not immediately clear.

The United Nations is not overseeing the transfer deal, which involves residents of the pro-government villages of Foua and Kfarya and the opposition-held towns of Madaya and Zabadani. All four have been under siege for years, their fate linked through a series of reciprocal agreements that the U.N. says have hindered aid deliveries.

Rami Abdurrahman, who heads the Britain-based Syrian Observatory for Human Rights, and Hezbollah’s Al-Manar TV, earlier said that 3,000 people will be evacuated from Foua and Kfarya, while 200, the vast majority of them fighters, will be evacuated from Zabadani and Madaya.

Abdurrahman and opposition activist Hussam Mahmoud, who is from Madaya, said the evacuation has been delayed. Abdurrahman said no permission was given for the evacuation while Mahmoud said it was delayed for “logistical reasons.”

Abdurrahman said Saturday’s blast — which hit an area where thousands of pro-government evacuees had been waiting for hours — killed 126.

No one has claimed the attack, but the Islamic State group and al-Qaida-affiliated Fatah al-Sham Front have targeted civilians in government areas.

United changes policy: Crew can’t displace seated passengers

CHICAGO — United Airlines is changing a policy and will no longer allow crew members to displace customers already on an airplane.

The change comes after a passenger, Dr. David Dao, was dragged from a fully booked United Express flight in Chicago because he refused to give up his seat to make room for crew members. Cellphone video of the incident sparked widespread outrage and created a public-relations nightmare for United.

The change outlined in an internal April 14 email says a crew member must make must-ride bookings at least 60 minutes before departure. Previously, crews could be booked until the time of departure.

A United spokeswoman said Sunday the change is part of a review of policies and it’s meant to ensure that situations like Dao’s never happen again.

Death toll rises in collapse of garbage mound in Sri Lanka

COLOMBO, Sri Lanka — The death toll from the collapse of a massive garbage mound near Sri Lanka’s capital rose to 26 on Sunday, and activists said 20 more people could still be buried underneath the debris.

Maj. Gen. Sudantha Ranasinghe, who is leading the rescue efforts, said authorities were struggling to determine how many people were trapped under the debris.

The mound collapsed Friday evening as people were celebrating the local new year. Ranasinghe said 78 houses were destroyed and more than 150 were damaged.

The site has been used to dump Colombo’s garbage for the past few years as authorities sought to give the capital a face-lift. But residents living in tiny homes in the area have protested against the waste dumped there.

Police search for Ohio man after killing shown on Facebook

Cleveland police and the FBI are hunting for a shooter who killed an elderly man and streamed it on Facebook Live.

“I found somebody I’m about to kill,” the man said in the video, as he pulled his Ford Fusion to the side of a road about 2 p.m. Sunday. “I’m about to kill this guy right here. He’s an old dude,” the man said as he confronted Robert Godwin Sr., 74.

“Can you do me a favor?” the man asked Godwin before asking that he say the name of a woman. “She’s the reason this is about to happen to you.”

The shooter, whom police suspect is Steve Stephens, 37, then asked Godwin’s age before killing him. The men did not know each other, police said.

Stephens said in the live video that he has killed more than a dozen people, police said.

N.Y. zoo gives long and short of newborn giraffe

HARPURSVILLE, N.Y. — April the giraffe’s calf is nursing strongly and his mother is recovering “perfectly,” said officials with Animal Adventure Park on Sunday after a morning veterinarian check with the newborn.

April gave birth to a healthy male calf Saturday at the privately owned Animal Adventure Park before an online audience of more than a million viewers.

The calf weighs in at 129 pounds and stands 5 feet 9 inches tall.

Seconds after birth, April tenderly licked her calf, which began to slowly pick up his head from the floor of the pen. About 45 minutes after he was born, he stood on wobbly legs while mom helped keep him steady.

At least 1.2 million people watched the Adventure Park’s YouTube streaming of the event.

A contest will be held to decide on the calf’s name.

Trump assails marchers for asking about his tax returns

WASHINGTON — President Donald Trump lashed out Sunday at the thousands protesters who took part in marches across the country on Saturday to demand that he release his tax returns, declaring on Twitter that “the election is over!”

As a candidate, Trump declined to release his tax returns — a practice followed by other presidential hopefuls since the 1970s — claiming he couldn’t do so because he was under audit.

“I did what was an almost an impossible thing to do for a Republican — easily won the Electoral College! Now Tax Returns are brought up again?” Trump said in one Sunday tweet.

In another, he suggested that someone “should look into who paid for the small organized rallies yesterday,” adding: “The election is over!”
