The Syrian army advanced within firing range of the rebels' sole supply route to Aleppo in heavy fighting Thursday despite its announcement of a ceasefire for the Eid al-Fitr holiday.
Saudi-backed rebel group Jaish al-Islam (Army of Islam) said four of its fighters were killed trying to stop the army from cutting the Castello Road, the only route into rebel-held areas of Syria's second city.
Regime bombardment of several opposition-controlled districts left 10 civilians dead, including three children, the Syrian Observatory for Human Rights said.
Rebel fire on the government-held Sayf al-Dawla neighbourhood meanwhile killed five people, including a child, the monitor said.
The army announced on Wednesday that it was observing a 72-hour nationwide ceasefire for Eid al-Fitr, which marks the end of the Islamic holy month of Ramadan.
But fighting has continued, particularly in and around Aleppo.
President Bashar al-Assad's forces have been trying to cut the Castello Road for more than two years and the Observatory said that Thursday's advance brought them the closest so far to achieving that goal.
Their capture of a hill just a kilometre (less than a mile) away allows them to fire on any traffic moving along the road from the ground as well as from the air, the Britain-based monitoring group said.
Islamist rebels immediately launched a counter-attack but had not been able to dislodge regime fighters from the strategic hilltop.
"If government forces can hold their positions there and fight back the counter-offensive, then the opposition neighbourhoods will be completely besieged," Observatory head Rami Abdel Rahman said.
The Castello Road wraps around Aleppo's eastern and northern edges then leads into rebel-controlled territory north of the battered city.
An estimated 200,000 people still live in the rebel-controlled parts of the city, which are regularly bombarded by government warplanes.

An AFP journalist in an opposition-held neighbourhood said shelling could be heard throughout the city's east, and that people who had travelled into Aleppo to visit their families for the holiday were stuck inside.
"On the first day of Eid, my family and I drove into Aleppo to see our relatives. We crossed the Castello Road very cautiously, without turning on the car lights," said Mohammad Yassin, a father of five.
The 43-year-old said he learned the road was "totally cut" on Thursday morning.
"I don't know what will happen and I'm scared the situation could stay like this for a long time," Yassin told AFP.
Syrian state news agency SANA on Thursday confirmed that regime forces were within firing range of the route after advancing in farmland north of Aleppo city.
Aleppo has been divided since mid-2012 when rebels seized the east of the city, confining government forces to the west.
According to an AFP photographer in the government-controlled parts of the city, there had been intense rebel rocket fire throughout the night on the western neighbourhoods.
It had calmed by the afternoon, but few residents were venturing out.
The pre-war commercial capital has been one of the main battlegrounds of Syria's civil war and successive ceasefires announced for the city have been swiftly broken.
Syria's government has pledged to retake the whole city despite efforts by Washington and regime ally Moscow to stem the violence there.
To the northeast, a US-backed alliance of Kurdish and Arab fighters advanced on Thursday inside a key town held by the Islamic State group, the Observatory said.
The Syrian Democratic Forces seized territory from IS jihadists in a southwestern district of Manbij, bringing them one kilometre (less than one mile) from the heart of the town.
More than 280,000 people have been killed and millions displaced since Syria's conflict erupted in March 2011 with anti-government protests.
World powers have thrown their weight behind a political settlement to the complex civil war, but UN-backed efforts to reach a transition have failed so far.
US Secretary of State John Kerry on Wednesday welcomed the 72-hour Eid ceasefire and said he was working with Russia and others to try to transform it into a lasting truce.
A landmark ceasefire announced by Russia and the United States in late February has mostly collapsed amid repeated violations.
