(CNN) -- A staff member of the aid organization Doctors Without Borders has died after an attack on a vehicle near the capital of South Sudan, the group said Friday.

The aid worker, Joseph, whose full name has been withheld at the request of his family, died two days after the attack, which took place Monday on a main road outside the capital, Juba, according to Doctors Without Borders.

Opinion: We need an Arms Trade Treaty now

A second employee of the organization was seriously wounded, the group said.

Doctors Without Borders, also known as Medecins Sans Frontieres, said the "exact circumstances" of the attack aren't yet clear, but the car in which its two staff members were traveling was "clearly marked as belonging to Medecins Sans Frontieres."

The organization has requested that South Sudanese authorities "investigate the brutal attack that resulted in the killing of our colleague," said Marcel Langenbach, director of operations for the group.

"We want to emphasize the need to respect international humanitarian law and on the obligation to ensure the protection of humanitarian workers, their property and health facilities," he said.

Doctors Without Borders said it had been working in the region for more than 30 years.

South Sudan officially gained its statehood in July 2011 after separating from Sudan.

CHAPTER XV--THE END OF THE MEETING

Stephen went on in her calm, cold voice:

'Did he tell you that I had asked him to marry me?' Despite herself, as she spoke the words a red tide dyed her face. It was not a flush; it was not a blush; it was a sort of flood which swept through her, leaving her in a few seconds whiter than before. Harold saw and understood. He could not speak; he lowered his head silently. Her eyes glittered more coldly. The madness that every human being may have once was upon her. Such a madness is destructive, and here was something more vulnerable than herself.

'Did he tell you how I pressed him?' There was no red tide this time, nor ever again whilst the interview lasted. To bow in affirmation was insufficient; with an effort he answered:

'I understood so.' She answered with an icy sarcasm:

'You understood so! Oh, I don't doubt he embellished the record with some of his own pleasantries. But you understood it; and that is sufficient.' After a pause she went on:

'Did he tell you that he had refused me?'

'Yes!' Harold knew now that he was under the torture, and that there was no refusing. She went on, with a light laugh, which wrung his heart even more than her pain had done . . . Stephen to laugh like that!

'And I have no doubt that he embellished that too, with some of his fine masculine witticisms. I understood myself that he was offended at my asking him. I understood it quite well; he told me so!' Then with feminine intuition she went on: What are the answers to this following set of questions: 1. Who has an unusual name for her gender?
2. Had she asked something of someone?
3. What was it?
4. Had he told someone about it?
5. Who?

13. How did she think he felt to be asked such a thing?
14. How did she realize this?
15. Did she continue to speak of it?
16. With what?
17. Did Harold feel that he was being abused in some way?
18. Could he escape it?

CHAPTER XX.

HOW CAPTAIN USSHER SUCCEEDED.

Late the next morning, Feemy and the other girls got up; they had slept together to make room in the house for the victorious Bob, but as Father John had prophesied, they were all too tired to be much inconvenienced by this. Immediately after breakfast the car came round, and Feemy, afraid to wish her friends good bye too affectionately lest suspicion should be raised, and promising to come back again in a day or two, returned to Ballycloran.

Thady was out when she got there, but he was expected in to dinner. Her father was glad to see her, and began assuring her that he would do all in his power to protect her from the evil machinations of her brother, and then again took his grog and his pipe. She went into the kitchen, and summoning Biddy, desired her to follow her up to her bedroom. When there, she carefully closed the door, and sitting down on the bed, looked in her attendant's face and said,

"Biddy, if I told you a secret, you'd never betray me, would you?"

"Is it I, Miss Feemy, that's known you so long? in course I wouldn't," and the girl pricked up her ears, and looked all anxiety. "What is it, Miss?--Shure you know av you tould me to hould my tongue, never a word I'd spake to any mortial about anything."

"I know you wouldn't, Biddy; that's why I'm going to tell you; but you mustn't whisper it to Katty, for I think she'd be telling Thady." What are the answers to this following set of questions: 1. Who left after breakfast?
