Attack on Mursitpinar crossing is latest attempt to prevent the arrival Peshmerga from Iraq to bolster Kobane defence.
Al Jazeera has gained access to the Syrian border town of Kobane after Kurdish forces recaptured it from the Islamic State of Iraq and the Levant (ISIL) group earlier this week.
Thousands of Kurds who fled the fighting have returned to their homes after four months of intense battles devastated the town.
But they now face the huge task of safely finding, and clearing, unexploded devices, as well as the threat of remaining ISIL fighters.
