Pakistani airstrikes in eastern Afghanistan killed 46 people, mostly women and children, a Taliban government official said Wednesday (Dec. 25), raising fears of further straining relations between the two neighbors. Hamdullah Fitrat, the deputy spokesman for the Afghan government, said those killed in the strikes that targeted four locations in Barmal, a district in the province of Paktika, were refugees, adding that six others were also wounded.

This came a day after Pakistani security officials, speaking on the condition of anonymity in line with regulations, told AP that Tuesday's operation was to dismantle a training facility and kill insurgents in Paktika. Earlier Wednesday, Mohammad Khurasani, the spokesman for the Pakistani Taliban or Tehreek-e-Taliban Pakistan, claimed in a statement that 50 people, including 27 women and children, died in the strikes. He said they were "unarmed refugees" who fled to Afghanistan because of Pakistan's offensive in the northwest. The TTP is a separate group but also a close ally of the Afghan Taliban.

China and Japan agreed to set up talks on often contentious security issues as they seek to improve a relationship riven in recent years by a range of issues, from territorial disputes to the discharge of water from Japan's tsunami-wrecked nuclear power plant. Japanese Foreign Minister Takeshi Iwaya, on his first trip to China since assuming the post in October, sounded positive after meetings with Chinese Premier Li Qiang and Foreign Minister Wang Yi, saying the talks were "very candid" and wide-ranging.

"I feel we were able to build a personal relationship that would lead to the future," he told reporters in the Chinese capital. Wang agreed to visit Japan next year for a high-level economic dialogue including cooperation on the environment, energy conservation and health and nursing care. Japan announced an easing of visa requirements for Chinese visitors, following China's recent decision to allow Japanese to enter without a visa.

Clashes between Islamists who took over Syria and supporters of ousted President Bashar Assad's government killed six Islamic fighters on Wednesday and wounded others, according to the British-based Syrian Observatory for Human Rights. It said the fighters were killed while trying to arrest a former official in Assad's government, accused of issuing execution orders and arbitrary rulings against thousands of prisoners. The fighters were from Hayat Tahrir al-Sham, or HTS, which led the stunning offensive that toppled Assad earlier this month.

Syria's transition has been surprisingly smooth but it's only been a few weeks since Assad fled the country and his administration and forces melted away. The insurgents who ousted Assad are rooted in fundamentalist Islamist ideology, and though they have vowed to create a pluralist system, it isn't clear how or whether they plan to share power. Since Assad's fall, dozens of Syrians have been killed in acts of revenge, the vast majority of them from the Alawite community, to which Assad belongs.

Azerbaijan observed a nationwide day of mourning for the victims of an air crash that killed 38 people and left all 29 survivors injured as speculation mounted about a possible cause of the crash that remained unknown. Azerbaijan Airlines' Embraer 190 was en route from Azerbaijan's capital of Baku to the Russian city of Grozny in the North Caucasus on Wednesday when it was diverted for reasons yet unclear and crashed while making an attempt to land in Aktau in Kazakhstan after flying east across the Caspian Sea.

The plane went down about 3 kilometers (around 2 miles) from Aktau. Cellphone footage circulating online appeared to show the aircraft making a steep descent before smashing into the ground in a fireball. Speaking at a news conference, Azerbaijani President Ilham Aliyev said that it was too soon to speculate on the reasons behind the crash, but said that the weather had forced the plane to change from its planned course.
