Turkey sent more troops, tanks and other military equipment on Monday to its border with Syria as Syrian President Bashar al-Assad\'s forces hit Syrian second largest city Aleppo in air and land attacks, Turkish semi-official Anatolia news agency reported. Armored infantry vehicles as well as missile launchers are among the recently-transported equipment deployed in Akcakale town of Sanliurfa province and Kilis province along the Syrian border, according to the report. Turkey, once a close ally to Syria, has imposed a series of sanctions, including an arms embargo, on the unrest-torn country due to its alleged crackdown on anti-government protesters. The Turkish-Syrian relations strained further after Syria shot down a Turkish military jet, which crashed into the Mediterranean Sea in June.
