ANKARA, Turkey — Syria's defense minister says the rebellion against President Bashar al-Assad's regime will be crushed.

Gen. Fahd Jassem al-Freij told state-run Syrian TV on Saturday that violence in the country will end soon, as troops are determined to bring back stability.

Al-Freij rarely makes public statements. His remarks came as Syrian troops launched a major offensive to retake rebel-held areas in the northern city of Aleppo and the central city of Homs.

In comments marking the anniversary of the 1973 Arab-Israeli war, al-Freij said the government is ready to give amnesty to rebels who "repent."

Another mortar shell from Syria struck Turkish territory on Saturday, prompting a fourth straight day of retaliatory artillery fire, and reviving fears that the crisis in Syria could spiral into a regional conflict.

The latest shelling comes a day after Turkish Prime Minister Recep Tayyip Erdogan called on Syria not to test Turkey's "limits and determination" and insisted that his country "was not bluffing" with its warnings.

The mortar landed in a rural area near the village of Guvecci, early  Saturday morning just minutes after intense fighting broke out between the forces of Syrian President Bashar Assad's regime and the rebels in the village of Harabjoz, in Syria's Idlib province across the border, the private Dogan news agency reported.

No one was hurt by the mortar, which landed some 500 yards outside of the village. But Turkish artillery based at an army battalion near Guvecci immediately responded with "counter-fire," the state-run Anadolu Agency said.

Villagers rushed out of homes and gathered at a safer point in the village, away from the border area.

The latest tensions with Syria began Wednesday when a Syrian shell hit a home at a Turkish border town, killing two women and three children and sparked unprecedented artillery strikes by Turkey.

Turkey's parliament on Thursday also voted to allow cross border military operations in Syria, further raising tensions between the neighbors that were once close allies.

On Friday, the U.S. sided with Turkey, condemning what White House spokesman Josh Earnest called the "aggressive actions of the Syrians." Earnest said Turkey's response was appropriate and that the U.S. stands by Turkey, a NATO ally.

Saturday's shelling came as both sides appeared to be trying to defuse the situation. A Turkish Foreign Ministry official said Friday that Syria has pulled tanks and other military equipment away from the border.

Turkey, along with other countries siding with the rebels, is averse to intervening militarily, while Assad has also tried to avoid provocations he believes would trigger a foreign intervention.
