Dozens of people were still unaccounted for Sunday following a deadly attack by Takfiri terrorists on Mozambique's northern town of Palma, while thousands of survivors were being evacuated to the provincial capital Pemba, various sources said.
Militants began attacking the town, a gas hub in the province of Cabo Delgado, on Wednesday, forcing nearly 200 workers, including foreign employees, to evacuate a hotel where they had taken refuge.
They were temporarily taken to the heavily guarded gas plant located on the Afungi peninsula on the Indian Ocean coast south of the Tanzanian border before being moved to Pemba.
Some residents of the town of around 75,000 people fled to the peninsula -- home of a multi-billion-dollar gas project being built by France's Total and other energy companies.
A boat that left Afungi on Saturday landed in Pemba around midday, according to police patrolling the city port.
According to a source close to the rescue operation, there were "about 1,400" people on board.
The evacuees included non-essential staff of Total and Palma residents who had sought refuge at the gas plant.
Several other small boats packed with displaced people were on their way to Pemba and expected to arrive overnight or Monday morning, according to humanitarian aid agencies.
Airport officials in Pemba said humanitarian aid flights had been suspended to free up space for military operations.
Caritas, a Catholic aid agency which is active in the province, also reported new arrivals to Pemba, located around 250 kilometers (150 miles) south of Palma.
- Shot in their homes -
"Now we await the arrival of people who are most vulnerable so that we can provide assistance," the local head of Caritas, Manuel Nota, told AFP.
Human Rights Watch said the militants indiscriminately shot civilians in their homes and on the streets.
"A rescue operation is currently underway. An unknown number of people died as they tried to flee Amarula hotel," Human Rights Watch regional director Dewa Mavhinga told AFP, adding their rescue convoy "was attacked by the insurgents".
The Mozambique government, which has not given any update on the attack since Thursday, is expected to give a news conference at 1700 GMT.
The militant attack on Palma is the closest yet to the major gas project during a three-year insurgency by Takfiri terrorists across Mozambique's north.
Since October 2017, extremist fighters have raided villages and towns in the region, forcing nearly 700,000 to flee their homes.
The violence has left at least 2,600 people dead, half of them civilians, according to the US-based data-collecting agency Armed Conflict Location and Event Data (ACLED).
A South African worker was killed in the Palma violence, according to a government source in his native country.
- 'Appalling violence' -
Martin Ewi, a senior researcher with the Pretoria-based think-tank, the Institute for Security Studies, said that "over 100" people were still unaccounted for.
"That's what we know so far, but it so confusing".
While local media reports said British workers may also have been caught in the attack, the UK's Foreign Commonwealth and Development Office said its embassy in Maputo was in "direct contact with authorities in Cabo Delgado to urgently seek further information on these reports".
"The UK wholeheartedly condemns the appalling violence in Cabo Delgado. It must stop," Minister for Africa, James Duddridge, tweeted.
The US, whose troops are helping train Mozambican troops fight the insurgency, said Sunday it "continues to monitor the horrific situation in Palma", adding one American citizen who was in Palma had been safely evacuated.
The embassy announced earlier this month that American military personnel will spend two months training soldiers in Mozambique.
