Seven people, including two US soldiers, have been killed in explosions in Afghanistan.
The deaths come as early results from historic elections gave President Hamid Karzai a strong lead over his rivals.
Three rockets were also fired in the capital, Kabul, injuring one woman and damaging an apartment building, in the latest of a string of attacks since last Saturday's poll.
Security experts had warned of a possible resurgence of violence after the election, which was largely peaceful despite threats of attack from loyalists of the hard-line Islamic Taliban regime ousted in late 2001.
