There has been an escalation of violence in Karachi which is affecting most parts of the city including the areas around the main road to the airport.
In the past week the number of people killed in political and sectarian clashes has increased and this has included a number of innocent bystanders.
It is likely that this violence will continue or increase further in the coming days. You should be particular vigilant at this time, keep a low profile, minimise movement around the city and avoid large gatherings or crowds.
