I read in this source that the past participle phrase is used in a passive sense, in which the action is done to the subject described by the phrase. It gives this example:
Exhausted by the morning's work, I got myself a cup of coffee and sat down.
But I've come across this news headline which seems to contradict that:
Bomb explosion hit Magallanes City, killed 7 and 9 others wounded.
Here, the past participle phrase killed 5 and 28 others wounded is done by the subject Bomb explosion. The rule(?) above says that the subject of the sentence must not be the doer of the action in the past participle phrase. Instead, it must be the receiver.
So I think it must be corrected to use the present participle to describe that the doer is the subject:
Bomb explosion hit Magallanes City, killing 7 and wounding 9 others.
Do you think the original headline is correct? How about my revision?
