EU hawks lead calls for tougher sanctions on Russia

BRUSSELS (Reuters) - European Union hawks on Russia, including Poland and Lithuania, called on Monday for sanctions on Moscow to be stepped up after a new offensive by pro-Russian rebels in eastern Ukraine, but EU power-broker Germany took a more cautious line.

The EU called an extraordinary meeting of foreign ministers for Thursday after separatists attacked Mariupol, a strategic Black Sea port, on Saturday with what NATO said was Russian support. Kiev said 30 civilians were killed.
