KABUL: A large explosion hit Kabul on Monday, hours after a suicide bomber blew himself up near a police checkpoint in the Afghan capital, Reuters reporters heard.

A police official said the blast appeared to come from a vehicle bomb near a compound for contractors close to the airport. There were no immediate details of damage or casualties.

It is the second blast of the day to hit the Afghan capital.

Earlier in the day, a suicide bomber on foot struck a street leading to Kabul's international airport. The attacks have coincided with a new effort to restart peace talks with the Taliban after earlier meetings were broken off last July.

Afghanistan's interior ministry spokesman Najib Danish had said that the target was a foreign forces convoy passing through the area but a police spokesman said he was not aware of that.

There was no immediate claim of responsibility for the attack.
