Human Factors; Procedure
The event occurred on the 280 degree radial/5 nm off the BOG VOR heading 100 degrees descending through 11;200 feet MSL. After being cleared for the planned/filed arrival (MQU1A) and passing the first point on the arrival (MQU VOR) approaching GIDRI (N0511.4 W07436.6); BOG Approach vectored us on a heading of 070 degrees. Approach then cleared us direct VULAM for the VULA2D arrival. After reaching VULAM and starting the turn towards DORSA; approach then vectored us to a 220 degree heading to intercept the 280 degree radial inbound to the BOG VOR; descend to 12;000 feet MSL. Approaching the 280 degree radial inbound; BOG approach then cleared us direct BOG VOR; cleared the ILS 13R; descend to 10;000 feet MSL. Approaching the BOG VOR on the 280 degree radial at 5 DME passing 11;200 feet heading 100 degrees; a 'Caution Terrain' aural warning was heard. The Pilot Flying (PF) immediately started a climb while the Pilot Monitoring informed ATC that we were in the climb for a terrain alert. Approach then said the minimum altitude in this sector is 12;000 feet. We leveled at 12;000 feet MSL; then approach re-cleared us for the approach. The PF intercepted the 134 course inbound and the glide path at 12;000 feet MSL and continued the approach and landing without further incident.Better situational awareness - ATC had vectored us off of two STARs and we were having difficulty understanding the controller which lowered our situational awareness significantly. Arranging for a definitive STAR well in advance followed by the approach and staying on the magenta line in accordance with the arrival and approach will enhance safety.

A flight crew reported poor ATC communications were a factor in receiving a GPWS terrain warning on approach into SKBO.
