Afghan security forces are facing almost daily attacks by Taliban militants, despite reported progress in efforts by the United States to broker an end to Afghanistan's nearly 18-year war.
The rush-hour explosion sent a plume of smoke into the air above the Puli Mahmood Khan neighbourhood of the Afghan capital and shook buildings up to two kilometres (1.2 miles) away, with the media reporter saying he could hear gunshots after the blast.
A plume of smoke rose over central Kabul shortly after midnight and sirens could be heard. Inside the embassy, employees heard this message over the loudspeaker: "An explosion caused by a rocket has occurred on compound."
Shelling and smoke could be seen around Ras Al Ayn on Friday morning, a day after Turkey and the US agreed to a five-day cease-fire in Turkey's offensive.
There have been a steady stream of arrests in Singapore related to support for extremism, and the affluent city-state's leaders have warned it is a prime target for an attack.
The United States imposed tariffs on a record $7.5-billion worth of European Union goods on Friday, despite threats of retaliation, with Airbus, French wine and Scottish whiskies among the high-profile targets.
