AMMAN - Air strikes on a camp housing Syrians uprooted by war killed 28 people near the Turkish border on Thursday, a monitoring group said, and fighting raged in parts of northern Syria despite a temporary deal to cease hostilities in the city of Aleppo.

The Syrian Observatory for Human Rights said the dead included women and children and the death toll from the air strikes, which hit a camp for internally displaced people near the town of Sarmada, was likely to rise.

Sarmada lies about 30 km (20 miles) west of the city of Aleppo, where a cessation of hostilities brokered by Russia and the United States had brought a measure of relief on Thursday. But fighting continued nearby and President Bashar al-Assad said he still sought total victory over rebels in Syria.

Syrian state media said the army would abide by a “regime of calm” in the city that came into effect at 1 a.m. (2200 GMT on Wednesday) for 48 hours, after two weeks of death and destruction.

The army blamed insurgents for violating the agreement overnight by what it called indiscriminate shelling of some government-held residential areas of divided Aleppo. Residents said the violence had eased by morning and more shops had opened up.

Heavy fighting was reported in the southern Aleppo countryside near the town of Khan Touman, where al Qaeda’s Syrian branch Nusra Front is dug in close to a stronghold of Iranian-backed militias, a rebel source said.

Government forces carried out air attacks on the area and rebels were attacking government positions around the town, pro-Syrian government television channel Al-Mayadeen and the Syrian Observatory for Human Rights said.  Pro-opposition media said an insurgent carried out a suicide bomb attack against government positions in Khan Touman.

A TV station controlled by the Lebanese group Hezbollah, which is fighting alongside the Syrian army, said the army used a guided missile to destroy a suicide car bomb before it reached its target in that area.

Elsewhere in Syria, fighting persisted. Islamic State militants captured the Shaer gas field in the east of the country, the first gain for the militants in the Palmyra desert area since they lost the ancient city in March, according to rebel sources and a monitor. Amaq, an IS-affiliated news agency, said Islamic State militants killed at least 30 Syrian troops stationed at Shaer and seized heavy weapons, tanks and missiles. Russian war jets were also reported to have struck militant hideouts in the town of Sukhna in the same Palmyra desert area.

Assad said he would accept nothing less than an outright victory in the five-year-old conflict against rebels across Syria, state media reported.

In a telegram to Russian President Vladimir Putin thanking Moscow for its military support, Assad said the army was set on “attaining final victory” and “crushing the aggression”.

The British-based Syrian Observatory for Human Rights said at least one person was killed overnight in rebel shelling of the Midan neighbourhood on the government-held side of Aleppo, which was Syria’s commercial hub and largest city before the war.

Twenty rockets fell on government-held parts of Aleppo on Thursday, state media said. But a resident of the rebel-held eastern part of the city said that although warplanes flew overnight, there were none of the intense raids seen during the past 10 days of air strikes.

People in several districts ventured onto the streets where more shops than normal had opened, the resident of al Shaar neighbourhood said.

Around 64,000 Syrians are stranded at the border with Jordan after intensified violence around Aleppo, Jordanian border guards said on Thursday.

The kingdom, which is already home to more than 630,000 Syrian refugees, introduced additional security checks at the Hadalat and Rokbane border crossings at the start of the year, leading tens of thousands more to congregate along the frontier.  “The number of refugees has hit 59,000 at Rokbane and it’s rising,” the head of Jordan’s border guards General Saber Al-Mahayra told reporters on Thursday.

Another officer told AFP that 5,000 others were massed at Hadalat, around 70 kilometres (40 miles) further west.

Mahayra said nearly 5,500 had arrived at Rokbane in the last 24 hours, an influx he attributed to increased fighting around Syria’s second city Aleppo, where more than 280 civilians have died in recent weeks.

Jordan has insisted it must screen newcomers to ensure they are genuine refugees and not militants seeking to infiltrate the country.

The kingdom is now allowing in only a few dozen refugees each day after screening.

According to Mahayra, around 2,000 Syrians currently camping near the border are suspected by Jordanian authorities of involvement with the Islamic State group.

Weapons have already been seized from some would-be refugees along the border, he added.

After Syria’s conflict erupted in 2011, Jordan initially kept open 45 crossing points along its 378 kilometre (235 mile) frontier.

But after a mass influx into the kingdom - Amman says the true number of Syrians in Jordan is closer to 1.4 million - there are now just five crossing points open, and three of those are reserved for the wounded.

Syria’s conflict began with anti-government protests but fighting quickly escalated into a multi-faceted war that has killed more than 270,000 people and forced millions from their homes.
