Fetching multiple urls with aiohttp in Python 3.5

Since Python 3.5 introduced async with the syntax recommended in the docs for aiohttp has changed. Now to get a single url they suggest:

import aiohttp
import asyncio

async def fetch(session, url):
    with aiohttp.Timeout(10):
        async with session.get(url) as response:
            return await response.text()

if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    with aiohttp.ClientSession(loop=loop) as session:
        html = loop.run_until_complete(
            fetch(session, 'http://python.org'))
        print(html)

How can I modify this to fetch a collection of urls instead of just one url?

In the old asyncio examples you would set up a list of tasks such as

    tasks = [
            fetch(session, 'http://cnn.com'),
            fetch(session, 'http://google.com'),
            fetch(session, 'http://twitter.com')
            ]

I tried to combine a list like this with the approach above but failed.
